Abstract

A simple leaky-wave antenna (LWA) array is presented here radiates in the boresight direction. It is based on uniform half-width (HW) microstrip leaky-wave antennas (MLWAs). Uniform HW-MLWAs usually radiate a fan-shaped beam with a beam direction near boresight at lower frequencies and near endfire at higher frequencies. One of the main challenges of uniform LWAs is to make them radiate toward the boresight. Six uniform HW-MLWAs are used in this array to overcome this limitation. The whole array is on a single substrate and is fed at the centre by a single probe. The peak gain of the array is 10.9 dBi and its 3dB gain bandwidth for boresight radiation is 270 MHz.
