In this research, a compact feeding circuit for an antenna that achieves three-way switchable beam directions using lumped parameter elements was designed and constructed by replacing the transmission lines of the conventional circuit with a phase shifter using lumped elements. The validity of the prototype was evaluated through measurements. In addition, the area has been reduced to 1/216 the size of a conventional one.
