A microstrip patch antenna with slots is designed and simulated for wireless portable devices. The proposed antenna has a simple structure with a common size of 70 X 20 mm in a 0.8mm thick FR4 substrate with a dielectric constant 4.4. With the proposed antenna structure the two wide operating frequency bands of 1.1 and 2.1 GHz can be achieved at 6.18dB gain can be used for GSM and UMTS networks. The return loss, gain and directivity, radiation patterns are measured and compared with a design without slots to prove the advantages of the presented antenna.
