Abstract
The Complementary Split-Ring Resonator (CSRR)-loaded crescent slot circular antenna is presented in this paper. The proposed antenna is resonating at 2.4[Formula: see text]GHz with the gain of 2.38[Formula: see text]dB. The antenna is designed for a predefined shape, which has a crescent slot, star-shaped small slots and spline split on a circle. The CSRR is carved on the ground surface of the antenna to acquire 2.4[Formula: see text]GHz and eliminates the multiple resonances created by various slots. The CSRR provides the miniaturization by shifting the resonance from 2.59[Formula: see text]GHz to 2.4[Formula: see text]GHz. The measured, [Formula: see text]6[Formula: see text]dB impedance bandwidth of the antenna is 11.25%. The antenna is fabricated using an FR4 ([Formula: see text]) substrate. The proposed crescent slot circular antenna is simulated using Ansys HFSS 17.0.
