Comparison between rectangular and triangular patch antennas array

In this paper, several designs of micorstip arrays antennas, suitable for wireless communication applications, are presented. This paper demonstrates several shapes of microstrip array antennas, such as rectangular and triangular patch antennas array. Specifically, 4?1, 2?1, and single element of both shapes are designed and simulated by a full wave simulator (IE3d). Moreover, this paper presents a comparison between both rectangular and triangular antenna arrays. Since, the resonance frequency of these antennas is 2.4 GHz; these antennas are suitable for ISM band and WLAN.
