A compact triple band antenna array for GNSS application, covers GPS L1, L2 and L5 frequency bands, is proposed in this paper. The array is comprised of 4 radiating elements spaced 0.47 wavelength apart (center to center) at the GPS L1 band and filled with dielectric material and three stacked patches. It is observed that due to the compactness of the antenna array the mutual coupling degrades the...
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, a meander line, three branches, and a ground plane with rectangle clearance region. The antenna is featured with several characteristics such as dual...

A novel quad band circular polarized stacked patch antenna has been designed for global navigation satellite systems. The presented antenna operates in the three GPS carrier bands (L1, L2, L5) and the 2.3 GHz frequency band. The stacked patch technique has been used while the antenna performances are analyzed in respect to the simulated s-parameters, radiation patterns and axial ratios. The antenna...
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...
