Abstract: This paper presents the design of an ultra-wide band (UWB) circular patch antenna with microstrip line feed and optimization of various antenna parameters. The antenna with dimension of (33 x 30 x 1.5) mm3 is fabricated on FR-4 epoxy substrate having permittivity constant εr=4.3, loss tangent tanδ=0.002. The designed antenna has the capability of operating in the bands (2.7-4) GHz, (6.8-12.5) GHz and (14.6-18) GHz. The antenna performance was modified by inserting a slot in the ground plane to achieve impedance bandwidth (S11<-10dB) in (2.7-20) GHz. The modified antenna was fabricated and tested using the vector network analyzer. The simulated and measured results are presented and compared. The feed line used has characteristic impedance of 50Ω.
