Abstract

This paper proposes a truncated arc patch antenna loaded with a novel complementary slotted split ring resonator (CSlSRR) in the ground plane. The antenna achieves wide bandwidth, circular polarisation (CP), and omnidirectional radiation pattern in the S-band. The electrical size of the antenna is 0.36λ₀ × 0.31λ₀, and the radiating metal dimension is 0.18λ₀ × 0.21λ₀ (λ₀ corresponds to f₀ = 2.45 GHz). Truncated corners with a semi-circular arc produce CP with the inset feed. The CSlSRR helps in improving the bandwidth and miniaturisation of the antenna. The design achieves a size reduction of 61%. The fabricated antenna exhibits 12.3% impedance bandwidth (IBW), 4.07% axial ratio bandwidth (ARBW), and a maximum gain of 2.476 dBi at 2.75 GHz. The antenna prototype is characterised in an anechoic chamber. The paper carries out a comparison of the measured and simulated results and other reported works in literature.
