Antenna beam shaping using a non-uniform array antenna

Abstract

To guarantee service quality, it is desirable to shape the antenna pattern so that it provides uniform gain over the intended service region. The beam shaping design example used in this paper demonstrates how the minimax algorithm shapes the antenna mainlobe to circular and elliptical beams and does so in such manner that the shape of the antenna mainlobe matches the geographical contour of the continental United States. The array antennas used in this simulation study are 148 and 244 non-uniformly spaced element antennas.
