Abstract :
Design and performance of an extremely wideband quasi-self-complementary pentagonal antenna with wireless local area network (WLAN) stop band have been analyzed in this paper. It consists of a pentagonal shaped radiator with its complementary structure, CPW feed line and two symmetric modified U-shaped slots in the ground plane. It is designed on RT 5880 dielectric material with relative permittivity of 2.2 and thickness of 3.175 mm. The predicated extremely wide impedance bandwidth is 2.78-15.85 GHz, for VSWR <; 2, with a stop band 5.08-6.11 GHz, for VSWR > 2. An extremely wideband is achieved by modifying ground plane and stop band is acquired by inserting slots in the ground structure. The dependence of antenna on the various parameters has been studied and results presented systematically. Significant gain reduction in the stop band is also observed with satisfactory radiation patterns.
