Two and four-element wideband Sectoral fractal array antennas with omni-directional radiation patterns

Abstract

Two-element and four-element sectoral fractal planar monopole antenna arrays for wideband communication applications is investigated. The proposed antenna structure is constructed by means of feeding two and four element omnidirectional Sectoral fractal patch elements with a 3-section 2-way Wilkinson power divider. The peak gain values of two-element and four-element array antennas are almost 3 dB and 6 dB higher than the single-element peak realized gain, respectively.
