✦ Synopsis

The stacked structure of an aperture-coupled cylindrical ( ) dielectric resonator DR antenna is studied experimentally. The effects of the offset and the air gap between the dri¨en and parasitic DR elements are in¨estigated. It is found that the bandwidth of the stacked structure can increase from the single-element ¨alue of 9% to 37%. The ¨oltage standing-wa¨e ratio, the radiation patterns, and the antenna gain are also reported.

We propose a dynamic technique for a microwa¨e holography system. We use a microstrip patch antenna in constructing the hologram and a new correlation method to reconstruct its digital form. The new reconstruction idea is based on the correlation between the hologram of point source and the hologram
