Abstract

In this paper, compact L‐shaped notched printed antennas with dual slits for multiband and wideband applications are presented. Here, an L‐shaped notch is cut on one side of the nonradiating edge of the rectangular patch with dual narrow slits cut on the other side. This patch is kept 2 mm away from the ground plane. The size of the ground plane is taken to be 38 × 10.8 mm^2^. Here, the study consists of the study of the proposed antenna with two types of ground planes, one with rectangular ground plane and the other with modified ground plane. Using rectangular ground plane, wideband and multiband operation is achieved with overall bandwidth of 6.84 GHz (110%). Again, by using modified ground plane, the overall bandwidth of the antenna is further increased to 7.86 GHz (114.5%). Moreover, the overall size of the proposed antennas is quite compact i.e., 38 × 38 mm^2^. © 2007 Wiley Periodicals, Inc.
