Abstract：

A　compact　circularly　polarized　microstrip　ring　antenna　is　presented　for　Global　Navigation　Satellite　systems　(GNSS)　application　in　this　paper.　The　antenna　consists　of　a　ring-shaped　slotted　ground　and　a　radiation　patch　which　is　fed　by　a　T-like　coupling　feedline.　The　radiation　patch　is　a　square　ring　strip　embedded　within　two　inverted　L-shaped　strips　and　a　rectangular　strip.　The　overall　size　of　the　proposed　antenna　is　0.38　×　0.38　×　0.038λ3g(λg　is　the　guide　wavelength　at　the　frequency　of　1575　MHz).　The　measured　−15　dB　|S11　|　bandwidth,　3　dB　axial　ratio　(AR)　bandwidth,　and　gain　bandwidth　of　larger　than　5　dBi　are　in　the　frequency　range　of　1552–1623　MHz,　which　can　fully　cover　the　operating　frequency　band　of　BDS　B1,GPSL1,　and　GLONASS　L1.　©　2020,　Electromagnetics　Academy.　All　rights　reserved.
