Printed MM-wave folded reflector antennas with high gain, low loss, and low profile

Abstract

The application of printed quasi-periodic structures to the design of printed folded reflector antennas has been demonstrated. To this end, use is made of the dual polarization properties of the printed structures. Results of two antennas were presented. The folded reflector antennas show very good radiation characteristics, low losses and a comparably low height. Consisting of two printed substrates only, they can be a promising alternative to conventional printed or slotted waveguide array antennas.
