Abstract :
In this paper a set of four low cost electrically small dual reflector antennas for radio-relay application are presented. The antennas use the same main and subreflector profiles integrated to distinct feed chains designed for each of the four proposed frequency bands. Significant theoretical analysis and preliminary experimental results in the 22 GHz frequency band indicate that the antenna design is compliant with the current Brazilian regulation for off-axis radiation.
