Abstract EN
In this paper, a compact circularly polarized (CP) antenna with omnidirectional radiation is presented, which has a central symmetric configuration (CSC) and planar structure.
It consists of three identical end-fire CP antenna units.
Based on the combination of two parallel complementary current sources, each unit cell can be realized by a scalloped cavity and a couple of curved strip lines.
Due to a single-layer circular structure with low profile, this configuration can be excited by a coaxial probe in the centre of the whole frame simultaneously.
In addition, this prototype was miniaturized with a diameter of 32 mm (0.266λr, the wavelength of the centre frequency in free space is represented by λr) and a height of 1.5 mm (0.012λr).
Centre resonance frequency 2.492 GHz is selected, resulting in an omnidirectional radiation and impedance bandwidth (VSWR ≤ 2) of 25 MHz (2481–2506 MHz).
