A planar split-ring resonator (SRR) antenna full/sparse array, fed by a Chebyshev distribution, is proposed in this paper. Following the Yagi principle, the antenna element consists of SRRs and an I-shaped resonator. The inclusion of the I-shaped resonator enhances coupling, resulting in high gain. Additionally, a 14 Ă 13 Chebyshev planar antenna array, based on corporate feed, allows for a non-uniform amplitude distribution to suppress side lobes. The proposed Chebyshev planar array exhibits high gain characteristics and low side lobe levels (SLL) in both the E- and H-planes. For sidelobes suppression further, by utilizing a genetic algorithm, a planar sparse array is constructed based on the proposed Chebyshev array. The measured gain of the array at 10.1 GHz is 22.4 dBi, with SLL values of â20.4 dB and â17.5 dB in the E- and H-planes, respectively. These results meet the requirements for wireless communication.
