Abstract:

The design of dual-frequency circularly polarized microstrip antenna fed by a single probe is studied.Miniaturization is realized by using slots,and broadband covering by loading the antenna with a patch.The proposed antenna is simulated by HFSS and the results of VSWR,AR,radiation pattern and gain are given,which shows that the antenna design is effective and feasible.

Key words: dual frequency microstrip antenna;circular polarization;small scale
