Design of a novel quad-band circularly polarized handset antenna

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 band operation, circularly polarized reception, low fabrication cost, compact size. Both of the simulated and measured results are shown to illustrate the good performance of the proposed antenna.
