Abstract

This paper introduces a compact dual-band circularly polarized (CP) slot antenna utilized for L-band Global Navigation Satellite Systems (GNSS) applications. The designed antenna structure is a printed L-shaped slot antenna (PLSA) fed by coplanar waveguide (CPW) with a squared ground plane. An L-shaped feeding line is protruded into an L-shaped slot to achieve a circular polarization operation. A reversed T-stub is adopted near the right center of the radiating patch in order to achieve a dual-band operation. The achieved fractional impedance bandwidths (FIBWs) are 5.6% (1.21-1.28 GHz) and 12.2% (1.46-1.65 GHz). The fractional axial ratio bandwidths (FARBWs) are 8.0% (1.21-1.31 GHz) and 18.0% (1.42-1.70 GHz) for the lower and upper GNSS ranges, respectively. The suggested antenna provides right-hand circular polarization (RHCP) radiation. The gain of the suggested antenna ranges between 3.0 dBic and 3.2 dBic for the lower and upper GNSS bands, respectively. The designed antenna exhibits a dual-band behavior that covers both the lower and upper GNSS bands. It has a low profile of 55 × 55 × 1.524 [mm]³ (0.22λ₀ × 0.22λ₀ × 0.006λ₀), which makes it suitable for incorporating within any portable devices receiving GNSS signals. The antenna is lightweight, small in size, simple structure, inexpensive, high FARBW, high FIBW, and demonstrates CP dual-band behavior with a single input. The antenna is simulated, fabricated, and measured. The measurements verify the numerical results successfully. The suggested antenna is suitable for GNSS applications due to its enhanced performance.
