Bottom fed planar elliptical UWB antennas

This paper describes the "bottom fed" planar elliptical dipoles. These antennas are electrically small ultra-wideband (UWB) dipoles with bandwidths on the order of 3:1 or better. Return loss is typically -14 dB, and boresight gain is nominally 3 Bi. Bottom fed planar elliptical dipole antennas are well suited for commercial applications.
