- Abstract
- A loop-type ground antenna, designed as a rectangular ground clearance connected by a capacitor, is proposed for mobile devices. The electromagnetic mechanism underlying the antenna operation is based on a new feeding method; a capacitor is used to cause a current loop to resonate at the operating frequency band. The proposed antenna is 5 x 3 mm and is easily implemented within mobile devices. The -10 dB bandwidth of the antenna is 400 MHz, from 2.3 to 2.7 GHz. The radiation pattern it produces shows omnidirectional performance on the horizontal plane.
