The Japan Aerospace Exploration Agency (JAXA) has planned to launch the geostationary satellite called Engineering Test Satellite-_VIII_ (ETS-_VIII_) in 2004. The antenna which is used for this experiment for mobile station will be put on a car roof. Therefore, A this antenna should be small, thin, cheap and of a simple structure. A phase shifter is not necessary and the beam is switched by use of a simple ON-OFF feeding method. In this paper, the switching circuit which can be used for the antenna is discussed. As for the characteristics, a miniaturized circuit with low insertion loss in order to pass the signal efficiently and satisfactory withstand power characteristics for the transmitting circuit are required.
