“…Numerous methods are in fashion to improve the ARBW of patch antennas and make them more versatile. The most popular method of obtaining CP is by incorporating dual orthogonal feed to the radiating patch [12,13]. The orthogonal feed can be designed by quadrature hybrid, ring hybrid, or Wilkinson power divider to name a few of the techniques.…”

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 0.36λ 0 × 0.31λ 0 , and the radiating metal dimension is 0.18λ 0 × 0.21λ 0 (λ 0 corresponds to f 0 = 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.
