Innovative Octave-band Double-In-Phase-Fed Franklin Antenna for V/E-band Applications

Abstract

In this paper, a new method is applied to the Franklin antenna concept in order to enhance the impedance bandwidth to more than an octave and retain the main beam direction in broadside mode within much more bandwidth with less than 3 dB gain fluctuation. Moreover, a very fine-shaped controllable fan-beam pattern is achieved using this technique.
