How you can Calculate a Monopole Length - Hardware RDTK

Calculate the length of a quarter wavelength monopole antenna for an ordinary 4G cell phone in the 2500 Megahertz band (for example). Use the formula: Length (feet) = 234 / Frequency (MHz). 234 / 2500 = 0.09 feet (rounded to nearest 0.1 foot.) In your attached image, formulas are written to calculate the length of monopole antenna which is quarter wavelength long (Different length for different frequencies as Lambda = light velocity. EXAMPLE of Whip Antenna Calculator: INPUTS : Frequency = 900 MHz, Length = 12 inches, Diameter = 0.5 inches OUTPUTS: Capacitance = -1.8 pF, Inductance = -17.28, Quarter Wavelength = 0.0833 meters, Antenna Length (%) = 365.75, Radiation Resistance = 347.5 Ohms Whip Antenna Formula. Following formula/equations are used in the Whip Antenna Calculator This can be understood since only half the voltage is required to drive a monopole antenna to the same current as a dipole (think of a dipole as having +V/2 and -V/2 applied to its ends, whereas a monopole antenna only needs to apply +V/2 between the monopole antenna and the ground to drive the same current) Most dipole antennas are a half wavelength long, and accordingly it is often necessary to calculate the physical length of a half wavelength dipole antenna. However the physical dipole length is not exactly the same as the electrical wavelength in free space - it is slightly shorter, and it is often necessary to calculate the dipole length as best as possible

How to calculate Monopole antenna Length exactly for given

monopole antenna impedance The simplest monopole antenna consists of a vertical element with an optimal length λ/4 on the ground plane. The radius and the shape of the ground plane will affect the radiation pattern and input impedance of the monopole antenna (usually r >>λ/4) This calculator can be used to design a Quarter Wave Ground Plane antenna, with radials. The radiating element is a quarter wave (λ/4) and the radials are 12% longer. There are usually four radials, three being a minimum, but you could use up to six Enter one (only one) value, the desired frequency or the antenna length in any length field. Click on Calculate and the opposite value will be displayed in feet and inches or frequency in megahertz (Mhz). These are considered as generic calculations and you may wish to use them to learn general information about the antenna structure you are contemplating. Click on Clear Values to prepare for new calculations

Click on Calculate and the optimum length for that combination will be displayed in feet, inches and fractions of inches, and in meters. To optimize the antenna for a frequency RANGE, do the calculations twice, once for the low end of the range and once for the high end; then average the two and plan to adjust the VSWR on both ends of the range as needed This calculator will help you to calculate the different wavelength of antennas based on the frequency.

antenna, but because of the very wide gain bandwidth of a quarterwave monopole, the antenna length is not too critical. But like any other antenna types, the gain of a quarterwave monopole will vary if parameters in the surroundings, such as case/box materials, distance t For example, if the length of the monopole antenna L − λ 0 /4, such that the corresponding length of the equivalent dipole antenna is λ 0 /2, the following values of the radiation impedances result: (6.168) Z monopole = 1 2 Z dipole = 36.5 Ω; Z foldedmonopole = 1 2 Z foldeddipole = 146 Ω

This formula to obtain the length of a half-wave dipole antenna will give a good ballpark value to start with I don't design these kinds of antennas and my books on the topic are at work, so I'm not sure, but you will find you already got into trouble with your length calculation. You used the speed of light in a vacuum to calculate the length. (notice the 'in a vacuum' part). On a PCB the wave will travel more slowly

Design notes: * The width of any antenna boom is included within the length of each dipole element, as one would do for any ordinary dipole or Yagi-Uda antenna. † The terminating stub \(Z_\text{term}\) is only required when the characteristic impedance of the feeder \(Z_\text{c,feed}\) is low. This is typical of VHF and UHF arrays. 6,8 A terminating stub improves the front‑to‑back ratio.

We use The typical manufacturing buzz-word is that terminated monopole and dipole antennas are traveling wave antennas and by some magic. monopole antenna and variants. However the desire to obtain a 50Ω feed impedance comes at a price. It is possible to calculate [4] the size of different vertical antennas, all having the same length of radiating element, but with varying diameters or numbers of wire

It is found that for a monopole antenna like a quarter wavelength vertical, the ground acts as a plane to reflect the radio waves so that an image of the top half of the antenna is seen in the Earth. It is possible to simulate this function by replacing the real earth with a conducting plane Effective Area of a Monopole. The receiving antenna in an AM car radio is a 1 m long monopole, vertical above the body of the car. AM reception is between 520 kHz and 1.6 MHz. Calculate the effective area of the antenna at the two extremes of the frequency range A whip antenna is the most common example of a monopole antenna, an antenna with a single driven element and a ground plane. The whip antenna is a stiff but flexible wire mounted, usually vertically, with one end adjacent to a ground plane antenna at a 90° angle, feedline coupling will distort the radiation pattern. With these ideas in mind, I began modeling antennas in search of an easy to build, all metal, vertical dipole array. The antenna that emerged from these modeling sessions consists of four vertical dipoles, each centered on a 60 inch vertical section. While th monopole with 4 radials is a primary example of the technique. The antenna is a monopole to the extent that effective radiation occurs only from the vertical leg of the structure. In principle, however, the antenna becomes an asymmetrical dipole in terms of the current on the various parts of the antenna

Dipole Antenna Length. When determining how long to make each leg of a Dipole antenna, dividing the frequency in MHz into 468 will give the overall length. To find the half wave, divide that number by two. This will give you the length of each leg of the antenna Bottom-Loaded λ/8 Monopole Antenna Radiation Resistance (Fig. 4E) The current distribution on a bottom-loaded eighth-wave monopole, Fig. 4E, is identical with the top half of the quarter-wave monopole which we folded over in the previous case, since the loading coil merely replaces the missing half In other words, an antenna loading coil is a lumped constant. On-line sources which state that a loading coil replaces a given physical length of an antenna, are in error! The reason we need a loading coil is simply this. The input impedance of any antenna shorter than a 1/4 wave length will exhibit capacitive reactance (-j) the antennas are thin and are in the far fields of each other. One antenna is a bottom-fed transmitting monopole. The other antenna is a receiving monopole that is base-loaded with a conjugate matched load. The gain of a hemispheric source is twice the gain of the corresponding isotropic source, a source radiating in all directions (Kraus, 1950)

(Also, for reasons we won't get into, the active length of the antenna is a bit longer than its physical length.) The dipole antenna has a more complex appearance than the whip monopole, but functionally it is simple. (Strictly speaking, a monopole is a dipole antenna where the earth functions as the mirror image of the monopole To calculate the wave length of a radio signal we take the Speed of Light in a Vacuum and divide it by the frequency in Hertz (the number of full wave cycles per second).. Wavelength (λ) = Speed of Light / Frequency The center frequency for my antenna design is 920 MHz so the wavelength is The 1/4 wave ground plane or monopole antenna in this instance will be mounted on a mast and therefore a perfect ground pane will not be present. The ground pane will be simulated as is normally the case with a number of metallic elements extending out horizontally from the base of the monopole element and connected to the shield of the coax
