Abstract

In this paper we present and investigate the concept of a novel smart microstrip E-shaped patch antenna for 3G handsets. The total radiated power and the overall gain performance of the proposed smart antenna is presented, analyzed and compared with the smart antennas consisted of rectangular patch. The smart antenna configuration for both cases is a linear array. In order to reduce the size of the antenna, which is incorporated into the backside of the handset, two antenna elements are considered with an inter-element spacing of a quarter wavelength (λ/4). The computer simulation results confirm that the antenna has a gain bandwidth of 10% for VSWR≤4. Moreover, the return loss S11 at 2GHz of the proposed smart antenna system is -20dB, a value that allows the E-shaped antenna to match easily to 50Ω source.
