| Abstract | A method of enhancing gain of a microstrip patch array antenna using a metallic horn structure for RADAR application is presented. A 4 by 1 linear microstrip patch array antenna operating in the frequency range of 24.05 – 24.25 GHz is first designed. A shunt connected series feed network, which has been widely used for commercial RADAR array antennas, is employed in this work. Next, a metallic horn structure is added along the two sides of the antenna in order to increase antenna gain. The effect of the folding angle of the metallic horn structure on the antenna performance, such as radiation patterns and gain, is investigated. |
