摘要：

An innovative counter-wound helical antenna with omnidirectional circular polarization (OCP) is reported in this communication, with a significantly enhanced radiation resistance and matching bandwidth compared with the conventional normal-mode CP helix counterpart. The antenna is realized by combining several helical radiators with opposite winding directions. A three-segment OCP counter-wound helix is studied, featuring one right-handed helix in the middle and two left-handed helices sandwiching it from the top and the bottom. Besides achieving a stable OCP pattern with gain variations of less than 0.2 dB, the radiation resistance at the operating frequency f(0) is increased to 26.7 Omega compared with 3.3 Omega of the traditional uniform-wound helix. Theoretical analysis and simulations are presented. To further enhance the radiation resistance, a five-segment helical antenna prototype is demonstrated and tested. The radiation resistance rises further to 80.9 Omega at f0 and the measured matching bandwidth reaches 2.8%, surpassing that of the conventional OCP helix by four times. Stable OCP radiation with a realized gain of up to 2.5 dBic is observed. Being compact and simple, the developed helical antenna could represent an ideal candidate for various wireless applications, for example, device-to-device (D2D) communications that require OCP radiations.
