In this paper, a single-feed arrow-shaped circularly polarized (CP) antenna is presented for GNSS application. Two orthogonally placed dipoles connected by phase delay lines are printed on both sides of a substrate to realize circular polarization. Further, an unbalanced slotted artificial magnetic conductor (AMC) is proposed to reduce profile of the antenna, enhance impedance bandwidth and CP bandwidth...
In this paper, the comparisons of four different Beidou B3 navigation antenna arrays with different radiation elements have been presented. For antenna elements, its size, bandwidth and gain properties have been observed. Then, four different four-element arrays constituted by different elements are presented. For these arrays, they have the same distance between elements and the same size ground...
