Abstract :
This paper describes a design of combline microstrip antenna to obtain a squinted, linearly polarized beam at very low cost. The antenna consists of travelling wave feed printed on low loss, low permittivity material. The electrical performance: bandwidth, radiation patterns and feed losses are examined and the effect of manufacturing tolerances are also discussed.
