Abstract
In this paper, a novel single-feed circular polarized planar antenna with its beam parallel to the substrate plane is discussed. This antenna is composed of two structures: It consists of a vertically polarized magnetic dipole implemented using short-circuited semicircular magnetic disks and a horizontally polarized bended complementary dipole. The entire structure is implemented on a single-layer paper honeycomb substrate with relative permittivity 1.08 and 0.6 mm thickness to resonate at 2.35 GHz. It achieves wide impedance and axial ratio (AR) bandwidths with good overlap and wide beamwidth. It has shown −10 dB impedance bandwidth of 11.5% (2.22–2.49 GHz) and 3 dB AR bandwidth of 11.06% (2.20–2.46 GHz). The proposed antenna would be promising for Wi-Fi or RFID applications.
