Abstract

A planar Vivaldi antenna structure with a core element is proposed for high gain. Techniques to achieve a
significant gain improvement over the full Ka (24-40 GHz) band are implemented; including a frequency-independent
excitation method, the introduction of logarithmic ripple on the lateral edges and enclosing the antenna in a dielectric
material.
