Abstract :
A broadband circular polarized two-element planar inverted-F antenna (PIFA) with pattern diversity and high isolation for multimode satellite navigation is reported. Circular polarization characteristic of the proposed antenna is achieved by introducing a cross branch at its corner of the ground. The modified PIFA structure gives the antenna a broadband impedance bandwidth characteristic. A prototype is fabricated and measured. The results show that this circular polarized antenna with compact dimension has broadband from 1.1 to 1.7 GHz and good isolation of 14 dB between the two elements over the whole band, which makes the antenna suitable for handheld terminal application of multimode satellite navigation.
