摘要： A loop type ground radiating antenna having dual resonance is disclosed. The antenna including a feeding path that traverses the ground clearance, creating a first portion and a second portion. One or more first capacitors are disposed along a first conductive path between the ground clearance and the edge of the ground layer, proximate the first portion, while one or more second capacitors are disposed along a second conductive path between the ground clearance and the edge of the ground layer, proximate the second portion. An input capacitor is used to feed the feeding path. The values of the input capacitor and the first capacitors determine a resonant frequency of the first feeding loop, while the values of the input capacitor and the second capacitors determine a resonant frequency of the second feeding loop. By proper selection of the capacitor values, a wide bandwidth may be created.
