Abstract :
A simple low-profile antenna with an enhanced gain is proposed for multiband orthogonal frequency-division multiplex (MB-OFDM) ultra wide band (UWB) systems. Using proximity coupling along the surface we demonstrate a technique to enhance the gain at lower UWB frequencies. The antenna is realized as a conventional CPW-fed printed disc monopole with unconventional metallic patches on the top of the substrate. With these metallic patches the antenna gain is improved especially at lower frequencies in the FCC UWB band, making it more suitable for MB-OFDM systems. Theoretical input reflection coefficient, antenna gain and radiation patterns are presented along with a complete parametric study of the proposed antenna.
