Abstract

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°. 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.
