Abstract :
A multi-band circularly-polarized microstrip antenna is designed in this paper. The antenna is made up of two patches. Both the patches are placed on one substrate. The centre patch with four T-shaped slits is aimed to obtain dual-band operation. The outer patch with two square slits can work at another band. The antenna is excited with two feeding points to satisfy the port isolation. The antenna is compact and easy to fabricate. Simulated and measured results show that the antenna can generate circular polarized in three bands and can satisfy satellite communication.
