To begin, it is important to comprehend the key principles underlying antenna design. Firstly, antennas are designed to maximize signal strength by efficiently radiating or capturing electromagnetic waves. This involves careful consideration of factors such as frequency range, gain, polarization, and radiation pattern. By optimizing each of these parameters, engineers can ensure effective transmission and reception while minimizing energy loss.

Next, let us delve into the impact that antenna design has on reducing power consumption in radio searching. When designing antennas for low power applications, several considerations come into play:
