Abstract :
In this paper, an electrically small normal-mode helical antenna (NMHA) with capacitive coupling feed has been proposed and studied. An equivalent circuit model of the antenna is proposed and analyzed to understand the working mechanism. Simulated results show the proposed the NMHA has pretty good impedance matching, radiation efficiency and good circular polarization.
