Abstract

A differentially compact dual circularly polarized (CP) concentric ring traveling wave-fed quasi-lumped resonator (QLR) array working at 5.8 GHz is presented. The array consists of seven series QLRs, each with an interdigital finger capacitor, connected by a parallel narrow-strip inductor. The CP was obtained by organizing the radiating QLR over a concentric ring-fed microstrip. The QLR was fed with a current of the same magnitude and some phase delay at each element. The dual-port feeding permitted the selection of the traveling wave direction and, consequently, the mode of CP. The measured bandwidth was 5.76-5.8 GHz at port 1. Meanwhile, the bandwidth was 5.75-5.77 GHz at port 2. The measured peak gain was 5.9 dBi at port 1 and 6.4 dBi at port 2. The cross-polarization was 19 dB lower than the co-polarization at port 1, which is a characteristic of right-hand circular polarization (RHCP). The cross-polarization was 14 dB higher than the co-polarization at port 2, which is a characteristic of left-hand circular polarization (LHCP). The size of each radiating element was 5.8 × 5.6 mm², and the array was 40 × 40 mm². These features and its compact size make the proposed array antenna a good candidate to be used in wireless systems.
