Abstract

A new feed structure with a loop-type radiator is proposed for achieving a wide bandwidth characteristic. The method for achieving a wide impedance bandwidth characteristic is to control the input impedance of the feed structure using a parallel capacitor and inductor. The size of the ground plane is 50 × 20 mm2, which is usually used as the ground for USB dongle applications. The size of the rectangular ground clearance for the loop-type antenna is 8 × 4 mm2. The proposed antenna was designed and measured using HFSS and a 3D CTIA OTA chamber. The center frequency is 2.45 GHz and the impedance bandwidth under VSWR = 2:1 is 550 MHz (2.18-2.73 GHz), which is adequate for long term evolution bands (7, 30, 40) and Wi-Fi applications.
