Abstract A directive antenna fed by a rectangular waveguide termination is presented in this paper. The antenna consists of a radiating slot associated with a focusing system made of a series of high‐dielectric slabs and air, forming successive Fabry–Perot cavities. Antenna gains as high as 19 dBi are obtained in this way, which can be used in microwave and millimeter‐wave links. Several antennas, based on a different number of cavities, have been built and tested at the center frequency of 38.9 GHz. © 2006 Wiley Periodicals, Inc.
