The term Antenna Gain describes how much power is transmitted in the direction of peak radiation to that of an isotropic source. Antenna gain is more commonly quoted than directivity in an antenna's specification sheet because it takes into account the actual losses that occur.
Master the antenna gain calculation with our interactive calculator. Clear misconceptions, explore practical applications, and elevate your wireless communication skills through understanding antenna gain.
In a receiving antenna, the gain describes how well the antenna converts radio waves arriving from a specified direction into electrical power. When no direction is specified, gain is understood to refer to the peak value of the gain, the gain in the direction of the antenna's main lobe.
10 lut 2015 · To better understand antenna gain, antenna designers utilize two dimensional, and three dimensional patterns to aid in proper antenna selection. These patterns provide system engineers a visual of how a specific antenna radiates.
25 wrz 2024 · This tool computes the Antenna Gain in dBi using: Antenna Factor (units: dB/m) Frequency of operation (units: Hz/kHz/MHz/GHz)
This calculator computes the gain of an antenna given its frequency, diameter, efficiency, and wavelength. This is useful for understanding the performance and effectiveness of an antenna in different conditions.
The gain of a real antenna can be as high as 40-50 dB for very large dish antennas (although this is rare). Directivity can be as low as 1.76 dB for a real antenna (example: short dipole antenna ), but can never theoretically be less than 0 dB.
