| Popis: | The design of a circular slot antenna for obtaining broadband circularly polarized (CP) radiation using a coplanar waveguide (CPW) feed is presented. The operation of the proposed antenna is achieved by protruding metallic mono-strip from the circular ground plane towards the slot center at ϕ = 0° and feeding antenna using a 50-Ω CPW with a protruded single strip at ϕ = 270°. In this design, the impedance bandwidth and 3 dB axial-ratio bandwidth can reach as large as 50 and 36%, respectively. The peak of antenna gain is about 3.9 dBi, with gain variations |
