摘要：

In this letter, a compact dual band monopole antenna with circularly polarized (CP) property around 2.4 GHz and linearly polarized (LP) property around 1.57 GHz is presented. The antenna consists of a tree-shaped monopole antenna and a modified grounded plane. To realize CP characteristic, two orthogonal monopole arms (arms A and B) with different lengths are used to generate a phase difference of 90 degrees. Another Y-shaped monopole (arms C and D) connected to the microstrip feed line is loaded to excite the LP mode. Compared with the previous Y-shaped monopole structure, the associated design has a significant improvement (about three times) in the axial ratio (AR) bandwidth and an excellent omnidirectional characteristic in the H-plane at around 1.57 GHz.
