Abstract:
A dual-operating-band planar horn antenna having
very low profile is presented in this paper. By opening a subwavelength
aperture into a corrugated conducting plate, good return
losses and a narrow radiated beam in each of the two desired operating
frequency bands can be measured. This behavior is very
similar to that observed in optical wavelengths where enhanced
transmission was measured through apertures etched in metallic
corrugated plates. Here, the double-corrugated structure has been
scaled into the microwave frequency range and the excitation has
been done by a conventional closed metallic waveguide placed in
the rear part of the structure. In this way, a new concept of a very
low profile feeder is proposed with potential wireless applications.
