In an antenna feed system, waveguide components serve as the critical interface between the transmitter/receiver and the radiating element (the antenna). Their primary function is to direct electromagnetic waves with extreme precision to ensure maximum gain and efficiency. Because they lack a center conductor, they avoid the dielectric losses common in other transmission lines, making them indispensable for , radar systems , and long-distance links . 2.
