High-gain and wideband aperture coupled feed patch antenna using four split ring resonators

초록

In this article, a high-gain and wideband antenna that is adapted arrays of four split ring resonators (4SRRs) in S-band was proposed. An aperture-coupled patch array antenna was designed with wideband characteristics and arrayed in the 4 x 1 with high-gain characteristics. To increase the gain more, arrays of 4SRRs based on metamaterial were used. The proposed metamaterial unit cell consists of four split ring resonators and an embedded capacitor to control the frequency characteristics easily. The proposed metamaterial's permeability was found to be near to zero. The proposed 4SRRs was arrayed and applied to the aperture-coupled patch array antenna. The proposed arrays 4SRRs resonators improve the antenna gain by 2 dB, between 3 and 3.4 GHz.
