A metamaterial inspired, slotted multiband patch antenna with reconfigurability

Abstract

In this letter the antenna is designed for achieving the multiband frequency configuration with the dimension of 26*26*1.6 mm3 with the use of substrate of dielectric constant of 4.4. It is capable of operating at the frequency of 3.9 GHz,5.8GHz and 6.7GHz, with a gain of 2.9dB,4.6dB,-1.5dB respectively. By using the method like DGS, Slots and SSRR structure, the design is able to generate and operate at the above mentioned frequencies. Furthermore by placing a metallic switch on the rectangular shaped slot the proposed antenna can also be used as reconfigurable antenna to produce different frequency.
