Ettorre, M. (author), Neto, A. (author), Gerini, G. (author), Maci, S. (author), TNO Defensie en Veiligheid (author)Planar leaky-wave antennas (LWAs) have received much attention in the recent years [1] for applications in the millimeter-wave ranges. In particular the compatibility with printed circuit board technology (PCB) and the low profile are the strongest features of these antennas. Mono dimensional planar leaky-wave antennas, as in [2], are...conference paper 2008
