“…Few antennas have been designed for multiband USB dongle applications [8]- [13]. In [8], a printed meander-line antenna is proposed for USB dongle devices, but it can only cover a 2.4 GHz WLAN band and is 60 mm × 20 mm including the ground plane. Dualband antennas for USB dongle applications are presented in [9]- [11], but it is a pity that these antennas can't cover the 3.5 GHz WiMAX band.…”

A miniaturized triple-band antenna suitable for wireless USB dongle applications is proposed and investigated in this paper. The presented antenna, simply consisting of a circular-arc-shaped stub, an L-shaped stub, a microstrip feed line, and a rectangular ground plane has a compact size of 16 mm × 38.5 mm and is capable of generating three separate resonant modes with very good impedance matching. The measurement results show that the antenna has several impedance bandwidths for S11 ≤ -10 dB of 260 MHz (2.24 GHz to 2.5 GHz), 320 MHz (3.4 GHz to 3.72 GHz), and 990 MHz (5.1 GHz to 6.09 GHz), which can be applied to both 2.4/5.2/5.8 GHz WLAN bands and 3.5/5.5 GHz WiMAX bands. Moreover, nearly-omnidirectional radiation patterns and stable gain across the operating bands can be obtained.

I. IntroductionWith the rapid development of personal wireless communications, the standards of wireless local area network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) have been widely applied to portable devices such as PDAs, laptops, and 3G smartphones. Almost all of these devices have adopted some USB ports for data exchanges and access to multiple wireless applications through wireless USB dongle devices. To implement the applications of wireless USB dongles, miniaturized antennas with multiple working bands that can be incorporated into compact USB dongles are needed. In this paper, a multi-resonant microstrip-fed antenna is proposed for wireless USB dongle applications. Compared to conventional multi-resonant antennas, the presented antenna has a much simpler structure, occupies less volume, and is easy to fabricate. By adjusting the geometries and sizes of the Lshaped stub and circular-arc-shaped stub, three separated good impedance bandwidths that can be applied to both the 2.4/5.2/5.8 GHz WLAN bands and the 3.5/5.5 GHz WiMAX bands are achieved. The measurements agree well with the simulations. The dimensions of the fabricated antenna are 16 mm × 38.5 mm, which makes it convenient for compact USB dongle devices. The thickness of the antenna is 1 mm. Moreover, the antenna has good radiation patterns and stable gains across the three working bands. II. Antenna Design 1. Antenna ConfigurationThe configuration of the triple-band monopole antenna is shown in Fig. 1(a). Figure 1(b) displays the photograph of the fabricated antenna. The circular-arc-shaped stub, L-shaped stub, and a 50 Ω microstrip line are printed on top of the FR4 substr...

“…Meander line technology allows designing antenna with a small size and provides wideband performance [2]. Having advantage to miniaturize antenna like other proposed methods [3] [4] [5], slotted meander line antenna is chosen because it is able to reduce the size of antenna. It is smaller and very flexible to be shifted or relocated [6].…”

“…Therefore, the numerous existing UWB antennas are too large in size to meet the requirements for internal antennas [2][3][4][5][6]. Recently, USB dongle antennas for WLAN [7,8] and UWB [9][10][11][12] applications have been reported and investigated. However, these antennas cannot cover enough bandwidth for both the WLAN and UWB frequency bands with the limited sizes.…”

Abstract-A miniaturized internal wideband antenna suitable for integration with the printed circuit board (PCB) of a wireless universal serial bus (WUSB) dongle is presented in this paper. The proposed antenna mainly consists of a folded metal plate with two sides beveled. By introducing a short-circuited pin connected to the system ground and etching a pair of slots in the bevel sides of the folded metal plate, a large impedance bandwidth from 2.4 GHz to more than 11 GHz is obtained, which easily covers the 2.4 GHz WLAN, WiMAX, S-DMB and UWB frequency bands. The effects of the short-circuited pin and the narrow slots on the impedance matching of the proposed antenna are investigated. The proposed antenna is easy to be fabricated by bending a sample metal plate due to its miniaturized geometry of 5 × 12 × 12.5 mm 3 . Details of the antenna design are described, and experimental results of the constructed prototypes are presented and discussed.
