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.

AbstractMetamaterials are artificial materials with negative permittivity and permeability. Metamaterials due to their unique negative parameter are capable of focusing the electromagnetic energy incident upon them. This focusing of electromagnetic energy is used to increase the gain of microstrip patch antenna. A capacitive loaded strip (CLS)-loaded split ring resonator is used to form a multilayer array of metamaterial and used in front of microstrip patch antenna to enhance far-field gain of antenna. An accurate simulation model is created and analyzed using CST. The simulated model is then fabricated and measured in fully anechoic chamber for validation. The far-field gain of regular patch antenna with and without metamaterial is measured in anechoic chamber. The increase in gain by 4 dB is measured at 95 mm from antenna. The beam focusing property is also evident from 3 dB beamwidth of antenna which is reduced to 42.01°.
