Double Slot Coupled Microstrip Antenna

Free registration required

Executive Summary

To improve the radiation performance a double slot coupled microstrip antenna has been proposed .The proposed antenna is based on the adjustment of the phase distribution in such a way that the phases should be added in one direction and cancelled out in the other direction. In upper half plane it radiates using stacked patch elements and the radiation of the slots are added and in the lower half plane the back radiation of the slots are cancelled with the front lobe of the side patch plates placed on the same side of feed-line. Thus it increases the front radiation and reduces the back radiation .The Front/Back ratio reported ranging from 27 to 33 dB using different stub length of the feed-line of proposed antenna.
