Circularly polarized microstrip antenna coupled on an asymmetrical cross coplanar slot
Résumé
A new compact multilayer planar structure is proposed to obtain circular polarization (CP) for the direct broadcast satellite (DBS) reception applications. The use of a circular planar antenna fed by asymmetrical coupling slot integrated on a coplanar−waveguide (CPW) feed line allows to achieve a 3dB axial ratio (AR) bandwidth greater than 2% and a −10dB reflection coefficient bandwidth greater than 20%. The antenna design is presented and the comparison between simulations and experimental results are done.
