Abstract
In this article, a novel antenna for a small universal serial bus (USB) dongle is proposed. A new feeding structure consisting of a feeding loop and resonant loop makes the whole USB dongle body radiate to fully cover Wi-Fi service. The proposed antenna has a bandwidth of 160 MHz, from 2376 to 2536 MHz with a voltage standing wave ratio of two. The proposed antenna consists of a feeding line, a capacitor (C), an inductor (L), and a ground plane. The basis for the radiating USB dongle is to form a resonating structure on a thin ground line of the USB terminal where current is strong and to use the ground plane of the USB dongle as a radiator. A new feeding structure was designed on a thin line which is the USB ground port of a USB terminal; it does not require additional clearance area. © 2015 Wiley Periodicals, Inc.
