Abstract

This investigation proposes a small ultra wideband (UWB) antenna for wireless universal serial bus (USB) dongle application. Halving the symmetrical triangle antenna to miniaturize antenna area and optimize the structure of ground and radiator, a new asymmetrical triangle UWB antenna is created. The impedance bandwidth of proposed antenna ranges from 2.77 to 10.64 GHz in measurement, which covers the whole UWB spectrum of 3.1 to 10.6 GHz. The designed antenna is easily integrated into a wireless USB dongle, which has dimensions of only 12 mm × 38 mm. Detailed simulations and experimental investigations were conducted to understand the antenna´s behavior and optimize the device for broadband operation.
