This paper describes a new compact single-feed, single-layer microstrip E-shaped patch antenna. It is an integrated array antenna and it is designed for a frequency range around 2.45 GHz ISM band. It is a symmetrical antenna suitably designed for WLAN application. This prototype was fabricated on a FR4 substrate with a relative permittivity of 4.7 and about 0.8 mm thickness. The aperture efficiency and gain of about 72 % and 6.7 dBi was obtained. It can be achieved by numerical algorithms for electromagnetic solutions like finite element method (FEM) and the method of moments (MOM) by using electromagnetic simulation software. For validation purpose CAD FEKO 6.1 suite is used. The bandwidth and gain achieved in the array antenna is 15 % greater than the single patch antenna.
