A passive antenna is an antenna that does not have an amplifier. They come in handy in applications that don’t require a long distance between antenna and receiver. The passive antenna contains radiating elements like a helix structure. It does not require any power supply, unlike the active antenna. What they require is an LNA on the signal receiver. Also, they work with a variable attenuator which decreases the electrical energy of the signal of the antenna without distorting the quality of the signal. It adjusts the power, provides isolation for certain components and lowers reflection interaction. The significance of…
