Antenna Gain Calculator

Antenna design and analysis require assessing antenna gain and antenna beamwidth. Our antenna gain calculator pairs effectively with the antenna beamwidth calculator, enabling you to optimize antenna performance.

How to Use the Antenna Gain Calculator

The Antenna Gain Calculator is a valuable tool for calculating the gain of your antenna based on input parameters. Antenna gain is an essential factor in antenna design and optimization, as it determines the amplification of the signal in the desired direction compared to an isotropic radiator. Understanding the gain of your antenna is crucial for achieving efficient and reliable wireless communication.

Instructions for Utilizing the Calculator

To utilize the Antenna Gain Calculator, follow these steps:

1. Frequency: Enter the operating frequency of your antenna in megahertz (MHz). The frequency parameter plays a significant role in determining the gain of the antenna.
2. Antenna Type: Select the type of your antenna from the available options. The options include Yagi, Dipole, Patch, and Parabolic.
3. Height: Specify the height of your antenna. Enter the height value and select the corresponding unit (cm, m, ft, or in) from the dropdown menu.
4. Transmitter Power: Input the transmitter power of your system in watts (W). The transmitter power is the amount of power radiated by the antenna.
5. Distance: Enter the distance between the antenna and the receiver in the desired unit (m, km, ft, or mi). The distance parameter affects the gain calculation.
6. Gain Mode: Choose the gain mode for the calculation. The options are Manual and Automatic.
7. Manual Gain (Optional): If you select the Manual gain mode, enter the antenna gain value in decibels isotropic (dBi).
8. Calculate Antenna Gain: Click the Calculate Antenna Gain button to initiate the calculation and obtain the gain of your antenna.

Antenna Gain Calculation Formula

The gain calculation in the Antenna Gain Calculator is based on specific formulas for each antenna type. The formulas used in the calculator are as follows:

Yagi Antenna Gain Formula: Gain = 8.1 + 10 * log10(frequency) + 20 * log10(height) - 0.81 * log10(distance)

Dipole Antenna Gain Formula: Gain = 2.15 + 10 * log10(frequency) + 20 * log10(height) - 0.36 * log10(distance)

Patch Antenna Gain Formula: Gain = 4.15 + 10 * log10(frequency) - 0.6 * log10(distance)

Parabolic Antenna Gain Formula: Gain = 29.7 + 10 * log10(frequency) + 20 * log10(height) - 37.6 * log10(distance)

Note: The formulas include logarithmic calculations based on the provided input parameters.
