Abstract :

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. Patch antenna loaded with metamaterial (MTM) is proposed for better reduction in the return loss at operating frequency 1.824 GHz. The proposed antenna is designed at a height 3.2 mm from the ground plane. At 1.824 GHz, the bandwidth is increased up to 22.7 MHz in comparison to RMPA alone of bandwidth 8.2 MHz. The Return loss of proposed antenna is reduced by -39.686 dB. Microstrip Patch antenna has advantages than other antenna as it is lightweight, inexpensive, easy to faicate and achieve radiation characteristics with higher return loss. CST MICROWAVE STUDIO is used to design the metamaterial based rectangular microstrip patch antenna.
