摘要：

A compact uniplanar antenna for 2.4 GHz WLAN applications is presented. This compact co-planar waveguide (CPW)-fed antenna has an advantage of excellent higher harmonic suppression. This characteristic is brought about by suitably inserting symmetrical slots in the ground plane of an open-ended CPW-fed transmission line. The proposed antenna with an H-shaped slot exhibits the characteristics of a centre-fed slot dipole together with excellent higher-harmonic suppression. The antenna designed on a substrate of dielectric constant 4.4 and height 1.6 mm offers moderate gain and good radiation characteristics. The design equations for the proposed antenna are validated in different frequency bands. Details of the simulated and experimental characteristics of the antenna are presented and discussed.
