Techniques to control the antenna aperture distribution to shape the far-field beam are very well known, and have found applications in traveling wave antennas  and conventional (beam scanning) leaky wave antennas (LWAs) [2, 3]. However, such techniques do not appear to have been applied to the symmetric (center-fed) LWAs for broadside radiation. In this paper, we first review the suitability of classical tapered distributions to the symmetric LWA. Secondly, the possibility of attaining partial aperture control using reflective terminations is introduced. And finally, measured results from a microstrip based LWA are presented and discussed.
