Microstrip antenna

Abstract

Abstract PURPOSE:To obtain a compact and light microstrip antenna and to execute the transmission and reception of plural frequencies with low loss by causing the plural slots of a ground conductor board to be respectively different in a length-wise direction and stereoscopically crossing respective microstrip conductors and the respective slots. CONSTITUTION:Two microstrip lines are respectively formed by microstrip conductors 2a and 2b and a ground conductor board 3 and the two microstrip antennas are respectively formed by slots 6a and 6b of the conductor board 3 and a microstrip patch conductor 5. The slots 6a and 6b are formed in a part to be just under the conductor 5 and the conductors 2a and 2b are stereoscopically crossed with the central part of the slots 6a and 6b. Then, the lengths of the slots 6a and 6b are made difference mutually. As a result, the resonance frequencies of the respective microstrip antennas are different and the respective antennas can be used as the antennas whose transmitting frequencies are mutually different.
