Broadband printed-circuit elliptical dipole antenna covering 750 MHz–6.0 GHz

The printed-circuit board (PCB) elliptical antenna with useful bandwidth covering from 750 MHz to 6.0 GHz is suitable for mobile, Bluetooth, wireless local area network (WLAN), the worldwide interoperability for microwave access (WiMax), and other wireless system applications. We present a low profile, PCB elliptical antenna design capable of achieving the above specified bandwidth. Swept frequency return loss, impedance and radiation patterns of this antenna have been measured. Design criteria for this elliptical dipole antenna are also investigated.
