ENHANCED DESIGN OF A TRIPLE-BAND MICROSTRIP PATCH-ARRAY ANTENNA USING A MULTI-SPLIT RING RESONATOR

Abstract

We have experimentally demonstrated and simulated an enhanced design of a triple-band patch array. The proposed antenna design is enhanced by merging multiple split-ring resonators (SRR) on a single-layer dielectric substrate. The proposed design works on reducing the footprint size with improved return loss, gain, and bandwidth compared with related works. The simulated results show that the proposed antenna operates at 5.96 GHz, 7.96 GHz, and 14.94 GHz and it agrees with the experimental results. High gain values of 9 dB, 6.9 dB, and 7.6 dB were obtained from the designed antenna with split ring resonators at those frequencies, respectively. The return loss for each frequency was -45.77 dB, -33.21 dB, and -45 dB, respectively. The outcomes show an agreement between the simulated and measured results with the fabricated antenna. The suggested antenna outcomes and analysis show that the antenna can operate within the KU and C bands, therefore it has potential applications in Wi-Fi, microwave devices, radar, and satellite communications systems
