Abstract
In this paper, the design of microstrip antenna for modern wireless communication is presented. The proposed antenna has a fairly good performance of impedance bandwidth at 2.40 GHz. The antenna is designed on size of 46 x 37x 1.5 mm(3) and fed with 50 Omega microstrip line. Satisfactory performance was obtained by using TLC 30 (TACONIC)substrate, allowing low cost production, Tightly controlled Dk, low Df, excellent dimentional stability and high flexural strength. It covers the frequency bands 1.37 and 2.40 GHz which includes GPS and WLAN. The proposed microstrip antenna for wireless communication, consists of two major combined radiating elements: a rectangular and triangular patch element. These two elements are interconnected by step and patch B-1 elements. It is found that the effect on frequency band depends on the length of the partial ground, position of steps, length of the rectangle and height of triangle in order to obtain a better S-11 value. The design antenna able to obtain power gain of 2.7 dBi. Results are obtained using CST Microwave studio.
