Miniaturization Design of Normal-Mode Helical Antenna Based on Capacitive Loading
This paper discusses the design of an electrically small normal-mode helical antenna (NMHA) with a capacitive loading and an innovative coupling feed structure. With this structure, the height of the helical antenna can be effectively reduced (0.064λ totally) while ensuring the mode of the antenna and high realized gain (2.02dBi). The electromagnetic analysis of a compact electrically small normal-mode helical antenna are presented. To understand the working mechanism, an equivalent circuit model of the helical antenna is proposed and analyzed. This innovative structure makes the antenna compact enough to be widely used in short-range communication devices. The simulated results of the antenna show that the proposed structure has a pretty high radiation efficiency, good impedance matching and high gain.
