A Study of A Circularly Polarized Electrically Small Antenna with Slender-shaped Back Conductor
Details
An electrically small circularly polarized normal mode helical antenna is presented. This antenna has a slender shap but it can generate circular polarization using a back conductor. The size of antenna is very small with a ka value of 0.35 at 1.12GHz. The measured and simulated characteristics of the antenna are in good agreement and attained a<3dB axial ratio bandwidth of 9.8% in measurement.
