A Square Tri Slit Slip Ring Resonator Integrating Novel RDRA for C-band Applications

Abstract

This paper proposes a square tri-slit slip ring resonator (STSSRR) integrated with a novel RDRA excited by a square ring with conformal strips. The proposed antenna is constructed on an FR4 substrate of 4.4 with overall dimensions of 46 x 46 x 1.6 mm³.The square ring is placed on the STSSRR-integrated RDRA, and three conformal strips are placed in the proposed design to enhance the impedance bandwidth. The proposed antenna operating band is 5.85 GHz to 7.3 GHz, with an impedance bandwidth of 22.05%. The antenna provides a high gain of 10.9 dB and an Radiation efficiency of 92% in the operating band. A perfect correlation was found between the Anritsu combinational network analyzer MS2037C measured and HFSS simulated results. The proposed antenna is used for communication, AMSAT, and defense satellite and C-band applications.
