Abstract

This paper suggests a CPW-fed UWB antenna with new hexagonal slot. To increase the impedance bandwidth of an antenna, the proposed antenna is designed with the hexagonal patch. Polygonal slot is inserted in the hexagonal patch to avoid interference with IEEE 802.11a. The proposed antenna was fabricated on FR-4 substrate with a relative dielectric constant 4.7 and thickness of 1.6 mm and measured for VSWR Characteristic and group delay. The fabricated antenna shows that the gain flatness is 4 dBi except at the band for IEEE 802.11a.
