Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>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 mm<italic>²</italic>, 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 mm<italic>²</italic>. 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. © 2015 Wiley Periodicals, Inc.
