A novel circularly polarized handset antenna which is compatible with multiple Global Navigation Satellite Systems is proposed. The antenna comprises a palm-size slab as the handset test bench, a small antenna chip mounted at the corner of the slab, three branches, a small patch, and a ground plane with rectangle clearance region. The antenna is featured with several characteristics such as quad frequency...
A broadband planar antenna with circular polarization is proposed, fabricated and measured. Circular polarization (CP) radiation of the proposed antenna is achieved by introducing a cross branch at its corner. And the modified PIFA structure gives the antenna a broadband impedance bandwidth characteristic. For ease in integration with active devices and design facilitation, the radiating element and...
