Abstract :
A compact internal wideband antenna suitable for integration with the printed circuit board (PCB) of a wireless universal serial bus (WUSB) dongle is presented in this letter. The proposed antenna mainly comprises a folded metal plate with two sides beveled and a short-circuited pin connected to the system ground plane. Within the short-circuited pin, the impedance bandwidth improved from 53% to about 136%, and a large measured operational bandwidth from 2.3 to 10.8 GHz is obtained, which easily covers the Wibro, WLAN, WiMAX, S-DMB, and UWB frequency bands. Due to the simple configuration and miniaturized geometry of 5 × 12.5 × 16 mm3, the proposed antenna is easy to be fabricated by bending a sample metal plate. Details of the antenna design are described, and experimental results of the constructed prototypes are presented and discussed. Moreover, the effects of a laptop on the radiation patterns of the proposed antenna are also studied.
