Abstract


Major operational disadvantages of microstrip antennas are their inefficiency and their very narrow bandwidth. One of a number of reasons for the expanded development of millimeter wave systems is related to a basic property of the antenna. Some antenna configurations have been proposed for such applications but these antennas have complex structure. Therefore, the design of new type of millimeter-wave antenna which is small, light, and economical for most users is absolutely necessary. So we have designed the antenna in this range of frequency. Thus the main objective of this paper is to increase the bandwidth and gain of the microstrip antenna using different shapes of conducting patch with beveled cut feed technique. In this paper, we have designed 4 element E-shaped antenna array. This array structure offers better bandwidth, gain and directivity with low return loss. E-shaped antennas are mainly used for millimeter wave communication. The proposed antenna offers bandwidth of 14.11 GHz with gain 7.54 dB. This antenna design can be simulated using ADS software. The Method of Moments (MOM) is used to design the E-shaped antenna and its array. In case of MOM technique which are used to find out the solution of Green’s function.
