Impedance Dependency on Planar Broadband Dipole Dimensions: an Examination with Antenna Equivalent Circuits
In this paper, the authors consider the connection between complex input impedance and the physical dimensions for planar Ultra Wide Band (UWB) antennas. The first time the effect of both the actual radiator width and length for impedance behavior is comprehensively presented. Also the effect of feed point dimensions on complex impedance is studied. The investigations involve both UWB single-resonant dipoles to cover bandwidth greater than or equal to 500MHz and a multi-resonant dipole for the entire Federal Communications Commission's (FCCs) frequency band of 3.1-10.6GHz.
