PROBLEM TO BE SOLVED: To provide an antenna system which can easily be made small-sized as a whole and suitably has its direction switched fast and a transmitter receiver using the antenna system. SOLUTION: A directional coupler is composed of a 1st dielectric line, which is formed of a dielectric strip 12 as an input/output part of a primary radiator 40 and a 2nd dielectric line, which is close to the 1st dielectric line and formed of a dielectric strip 13, and a means is provided which varies the relative position relation between a dielectric lens 2 and the primary radiator by moving the 1st dielectric line and primary radiator, while maintaining the connection between the 1st dielectric line and 2nd dielectric line. Consequently, a radiation beam is tilted. |
