A planar split ring resonator antenna array fed by Chebyshev network
A 13×14 planar split ring resonator (SRR) antenna array with the Chebyshev feed network is proposed. This antenna array consists of antenna elements and a Chebyshev feed network. Based on the principle of the Yagi antenna, the radiating patch is designed as an antenna element of the director with the metal ground being the reflector. The radiating patch is composed of three SRRs, an I-shaped resonator and two circular monopoles to enhance the radiation capability of the antenna element and improves the antenna gain. The feed of the antenna element is composed of arc monopoles, which improves the flexibility of adjusting the impedance matching. Furthermore, the calculation of the current matrix is used to guide the design of the Chebyshev feed network, and the non-uniform current distribution is used to reduce the side lobes. Moreover, the antenna element substrate is vertically erected on the substrate of the feed network to reduce the aperture size of the array with the feed network. Finally, the antenna array achieves a high gain of 22.3 dBi and low sidelobe level of -16 dB and -17.66 dB in E-plane and H-respectively.
