What are the applications of Effective Aperture of Lossless Antenna?
This concept is often used in antenna theory and design to calculate parameters like gain, directivity, and effective isotropic radiated power (EIRP) based on the physical characteristics of the antenna. In practice, lossless antennas are an idealization, and real-world antennas may have various losses, such as dielectric losses, conductor losses, and efficiency losses, which reduce their effective aperture and overall performance.
How to Calculate Effective Aperture of Lossless Antenna?
Effective Aperture of Lossless Antenna calculator uses Effective Aperture of Lossless Antenna = Antenna Aperture Efficiency*Physical Area of an Antenna to calculate the Effective Aperture of Lossless Antenna, Effective Aperture of Lossless Antenna represents the portion of the aperture that captures or radiates energy without loss. In a lossless antenna, all the energy that falls on the physical aperture is effectively used for transmitting or receiving signals, and there are no losses within the antenna system. Effective Aperture of Lossless Antenna is denoted by A_{e} symbol.
How to calculate Effective Aperture of Lossless Antenna using this online calculator? To use this online calculator for Effective Aperture of Lossless Antenna, enter Antenna Aperture Efficiency (η_{a}) & Physical Area of an Antenna (A) and hit the calculate button. Here is how the Effective Aperture of Lossless Antenna calculation can be explained with given input values -> 21.7 = 0.7*31.
