Optimization of a double — T microstrip antenna in order to obtain a largest bandwidth

In this paper a novel of a double - T microstrip antenna, which consists of two T - shaped monopoles is presented. The proposed antenna gives a two bandwidth eg. for wireless local area network (WLAN) operations, with bandwidth of 2,2-2,6 GHz and 5,6-5,9 GHz for S
₁₁
<; 10dB (WFS <; 2). The proposed antenna has o low profile and can easily be fed by using 50 Ω microstrip line. Good radiation characteristic of the proposed antenna have been obtained. In this novel the optimization was made to obtain the largest bandwidth.
