Compact Frequency-Notched Wideband Planar Monopole Antenna with a L-Shape Ground Plane

A wideband planar monopole antenna with an L-shape ground plane is presented. The antenna also has a frequency-notching characteristic. By etching a half-wavelength U-shaped slot in the interior of the radiation element, the frequency-notching characteristic is created. This paper presents the design and experimental results of the proposed antenna. Moreover, this study also investigates the tuning effects of the geometry parameters on impedance matching. © 2005 Wiley Periodicals, Inc.
