The proposed active electrically-small antenna design can radiate wideband HF signals with bandwidths of 24 kHz or more, with total efficiencies up to 80%, and radiated power levels approaching 100 W, by integrating a highly-efficient, class-E switching circuit with the antenna.
An ultra-compact wearable antenna with an artificial magnetic conductor (AMC) is designed and fabricated for a 24 GHz electronic travel aid (ETA) system. The AMC-antenna combination reduces the backward radiation to the user while improving the antenna's radiation properties and bandwidth without increasing its area.
