نویسنده
چکیده
In this present work, Rectangular Microstrip Patch antenna loaded with symmetrically cut H and hexagonal shaped metamaterial (MTM) is proposed for better improvement in the impedance bandwidth and reduction in the return loss at operating frequency 1.794 GHz. The proposed antenna is designed at a height 3.2 mm from the ground plane. At 1.794 GHz, the bandwidth is increased up to 27 MHz in comparison to RMPA alone. The Return loss of proposed antenna is reduced by 20.7dB. 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. KeywordsRectangular microstrip patch antenna (RMPA), Metamaterial (MTM) Impedance Bandwidth, Return loss.
