Abstract :
This paper presents a practical design of a high-gain cavity resonance antenna having highly reflective superstrate surface. To this end, the antenna is modeled using the transverse equivalent network (TEN) method, first. Peak directivity of 21.7 dBi at boresight is achieved in this modeling. Next, a full-wave analyzer software package based on moment method (Ansoft Designer v4.0) is employed to analyze the antenna structure. Peak directivity of 21.87 dBi at boresight is obtained using this analysis. Then, the actual antenna is fabricated and tested. Peak gain of 19.8 dBi at boresight is obtained in experimental measurements. The sources of discrepancies between these results are pointed out.
