Summary:
This paper presents a new radiation method for exciting small size Universal Serial Bus (USB) dongle applications. New radiation method is designed on a thin line that fully covers Bluetooth and Wireless Lan (Wi-Fi) services. The simulation of the proposed antenna has a bandwidth of 123 MHz, from 2388 MHz to 2512 MHz under Voltage Standing Wave Ratio (VSWR) = 2 : 1. The proposed antenna consists of a feeding line, capacitor (C) and inductor (L). The basis for radiating USB dongle is to form a resonating structure on a thin line connecting USB dongle and Printed Circuit Board (PCB) ground of an external device, where current is strong. The antenna is designed on a Frame Retardant Type 4 (FR-4) substrate (ε r = 4.4, tan δ = 0.02) and occupies area of 2.5 Ⅹ 7 mm2 . New feeding structure was designed on a thin line, which is the USB port of a USB dongle that does not require additional clearance area.
