Abstract
A dual planar inverted-F antenna (PIFA) with isolation enhancement for wireless USB dongle is proposed. The antenna, which consists of two identical PIFAs, is used for multiple-input-multiple-output (MIMO) system. The two PIFAs are allocated to the top and bottom layers of the USB dongle respectively, and are merged together through two vias connected to the ground planes to enhance the antenna isolation. The antenna structure is very simple and suitable for small USB dongles. Good isolation is obtained in the frequency band of 2.5-2.69GHz for IEEE 802.16e worldwide interoperability for microwave access (WiMAX) applications. Details of the design and simulation results are presented and discussed.
