In this paper, the authors propose three different micro strip antenna designs are investigated. The first design is a simple micro strip patch antenna. The second design is a multiband antenna and consists of the first structure micro strip patch antenna having a circular slot with one arm. The third design is also a multiband antenna. It is a modification of the second one and consists of a Split Ring Resonator (SRR) loaded in the ground plane exactly behind the patch. The first structure resonates at 14GHz. The second and third structures show four frequency bands at 5.8GHz, 11GHz, 13.4GHz and 15.4GHz, but there is an improvement in gain, bandwidth, return loss and VSWR (Voltage Standing Wave Ratio) by using an SRR in the third structure.
