Abstract

An efficient electrically small loop antenna includes a radiation device, an impedance matching network, and a connector that interfaces to associated electronic circuitry. The radiation device includes a conductive planar base element extending in a base plane and a conductive loop connected to the planar base element. The loop connects to the base element so that the electrical current for the antenna flows through both the conductive loop and the planar base element. The impedance matching network matches the radiation device to the associated electronic circuitry. The matching network is integrated into the planar base and is connected to both the conductive loop and the base element so that the electric current supplied to the antenna is conducted through both the base element and the conductive loop.
