Modified Elliptical Antipodal Vivaldi Antenna with Elliptical Tapered Slot Edge and Circular loads
This letter presents a new design of an ultra-wideband Elliptical Antipodal Vivaldi antenna with elliptical tapered slot edge and circular loads. A new empirical formula for the ground structure was proposed for ease of design. The fabricated prototype has proven better low cut-off frequency performance in term of return loss, gain and radiation pattern throughout a bandwidth from 730 MHz to over 20 GHz with good radiation characteristics.
