Compact reconfigurable dual frequency microstrip patch antenna for 3G and 4G mobile communication technologies

We propose in this article, a novel compact reconfigurable patch antenna with frequency diversity. This antenna can be tuned by changing the switching mode of two PIN diodes from the ONON state to OFFOFF state to switch it over two different mobile communication technologies, namely 3G and 4G. The antenna has a simple geometry and a small structure, its dimensions are 45 x 38 x 1.5 mm3 and it is printed on an FR4 substrate with a thickness of 1.5 mm. The prototype of this antenna has been fabricated and tested. The measurement results confirmed the simulation predictions in terms of frequency diversity performances.
