A wideband circularly polarized crossed monopole antenna for handheld terminals operating at UHF band is presented. Two quasi-orthogonal monopoles loaded with meandering lines of unequal end-length are employed for compact low-profile design. A feeding network composed of an unequal power divider and ${\text{90}}^{\circ}$ phase shifter is meant for achieving wide operating band and circularly polarized...
In this paper, a novel low-profile circularly polarized crossed dipole antenna operating at UHF band, with small dimensions of 180 mm × 160 mm × 4 mm ( 0.22 λ × 0.20 λ × 0.005 λ) where λ is the wavelength corresponding to resonant frequency 370MHz, is proposed. Meandering lines are designed to reduce the size of the antenna. To achieve circularly polarized radiation pattern, a feeding network composed...
