Rectangular-waveguide-excited short backfire antenna with corrugated rim
Abstract
The letter presents experimental results at X-band for a short backfire antenna with corrugated rim, which is excited by a rectangular waveguide. It is shown that the use of the waveguide feed can lead to a compact antenna having a directive gain of 20 dB, sidelobe levels of -17 dB and vswr in the range 1.1-2.
