Abstract :
The directivity and its bandwidth properties of Fabry-Perot resonator antennas made of two different ground plate covered with a partially-reflecting surface are studied theoretically, respectively. The relationship between the directivity and the primary source location is also obtained. It is shown that the directivity of Fabry-Perot resonator will obtain its maximum when primary source is located at certain of position. But the directivity bandwidth will not vary obviously with the source location. At the same time the product of maximum of directivity and its bandwidth is a function of reflection coefficient of partially reflective surface, which is larger than a certain constant. Finally the simulated results of planar Fabry-Perot resonator antenna are validated to have good agreement with the calculated theoretically.
