Abstract
In this paper, we propose a slotted waveguide array antenna covered by a dielectric slab with a post-wall cavity. The impedance matching of a resonant series slot array antenna based on a standing wave excitation can be easily achieved. Moreover, it is shown that the pattern shape of the proposed antenna is greatly improved and the directivity is enhanced by using the post-wall cavity.
