AbstractIn this paper, a miniaturized microstrip patch antenna using a negative index metamaterial with modified split-ring resonator (SRR) unit cells is proposed for ultra-wideband (UWB) applications. The new design of metamaterial based microstrip patch antenna has been optimized to provide an improved bandwidth and multiple frequency operations. All the antenna performance parameters are presented in response-graphs. Also it is mentioned that the physical dimensions of the metamaterial based patch antenna are very small, which is convenient to modern communication. A 130 % bandwidth, covering the frequency band of 2.9–13.5 GHz, (for return loss less than or equal –10 dB) is achieved, which allow the antenna to operate in the Federal Communication Commission (FCC) band. In addition, the antenna has a good radiation pattern in the ultra-wide band spectrum, and it is nearly omnidirectional.

In this paper, we study behavior of Ultra wideband antenna which is Rectangular Slotted Microstrip Patch Antenna. Then, the antenna operated in proximity of human arm model. Furthermore, the antenna is designed on a FR-4 substrate with dielectric constant of 4.3 and thickness 1.6 mm. This antenna simulated in CST Microwave Studio software. In order to test the antenna, an arm model was numerically modelled. The study shows properties and performances of antenna when it is placed in three situations which in free space, outside and inside of human arm model. The properties of UWB antenna in term of return loss, gain, directivity and radiation pattern in the three situations is simulated and discussed.
