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 20dB, sidelobe levels of ¿ 17 dB and v.s.w.r. in the range 1.1¿2.
