Abstract :
In this letter, a wideband single-feed circularly polarized (CP) patch antenna having conical radiation pattern is presented. The proposed CP patch antenna has a lower notched circular patch with a capacitive feeding and an upper parasitic notched patch. The antenna has a common 3-dB axial ratio and 10-dB impedance bandwidth of 10%.
