Abstract
In this present work, “Design and analysis of patch antenna using metamaterial (MTM) structure” is proposed for better improvement in the impedance bandwidth and reduction in the return loss at operating frequency 1.89 GHz. The proposed antenna is designed at a height 3.2 mm from the ground plane. This design is operated at 1.89 GHz and 2.553 GHz. At 1.89GHz, the bandwidths are increased up to 29.2 MHz and 19.8 MHz in comparison to 10.1MHz of RMPA alone. The Return loss of proposed antenna are reduced by 32.64dB and -29.26dB at dual band frequency as comparison to -10.26 dB of RMPA alone. Microstrip Patch antenna has advantages than other antenna is lightweight, inexpensive, easy to fabricate and achieve radiation characteristics with higher return loss. CST MICROWAVE STUDIO is used to design the metamaterial based rectangular microstrip patch antenna. Keywords- Rectangular microstrip patch antenna (RMPA), Metamaterial (MTM), Directivity, Impedance Bandwidth, Return loss, Gain.
I. Introduction
In the recent years the development in communication systems requires the development of low cost, minimal weight, low profile antennas that are capable of maintaining high performance over a wide spectrum of frequencies. The future development of the personal communication devices will aim to provide image, speech and data communications at any time, and anywhere around the world. This indicates that the future communication terminal antennas must meet the requirements of multi-band or wideband operations to sufficiently cover the possible operating bands. The performance of the fabricated antenna was measured and compared with simulation
