Multiband Planar Antenna Employing Open Complementary Split Ring Resonator Metamaterial Element

Abstract

A concise patch antenna with three frequency bands is presented. The design of the antenna utilizes Open Complementary Split Ring Resonators (OCSRRs) and aims to provide various wireless communication applications such as Worldwide Interoperability Microwave Access, Wireless Local Area Network (WLAN) and C-band frequencies. The utilization of a patch antenna with a partial ground plane proves suitable for the coverage of WLAN (2.67GHz-5.47GHz) frequencies. In order to attain resonance at both WiMAX (3.43GHz) and C-band (4.18GHz) frequencies, an OCSRR is incorporated into the design of the patch antenna. To attain effective impedance matching and enable multiband operation, the circular patch antenna incorporates OCSRRs. The dimensions of the antenna measure $\mathbf{23}\times \mathbf{23}\times\mathbf{1.6}\ \mathbf{mm}^{\mathbf{3}}$ , encompassing an overall size that allows for Omni-directional coverage across all three frequency bands. The prototype of antenna is designed and simulated using HFSS. The results are being validated through a parametric study of OCSRR. The bidirectional pattern is acquired when observing the plane at $\mathbf{\Phi}=\mathbf{90}$ degree, while the azimuthal plane corresponds to obtaining an omnidirectional radiation pattern. The proposed antenna possesses several beneficial characteristics, such as its compact dimensions, ability to operate across multiple frequency bands, and efficient impedance matching.
