Abstract

In this paper, a microstrip planar antenna with notch bands at 3.5/5.5 GHz is proposed for ultra- wideband communication. An e-shape parasitic slit and an inverted C-shape slit are imprinted beneath the radiating patch to generate notch bands to suppress the interference from WiMAX and WLAN respectively. The experimental results confirmed that the fabricated prototype with a very small size has achieved an UWB operating band for VSWR ? 2 with two notched bands covering frequencies of 3.32 - 3.76 GHz and 5.2 - 5.92 GHz. The presented design achieved a good gain except at notched bands and exhibits stable omnidirectional radiation patterns. In this design, filter elements are embedded only on one side of the substrate without cutting any slot/s in the radiating element/ground plane and no modification of the patch or the ground plane is required which gives the proposed design an advantages over many designs reported for the same applications.
