Abstract :
Horn antennas with peripheral chokes are used as feeds for reflector antennas in satellite TV receivers for C-band operation. A microstrip antenna (MSA) is proposed which can replace the existing horn feed. The advantages of this feed are compact size, reduced cost, reduced volume and weight, integration of the required electronics on the same substrate and small aperture blockage. Although MSAs are known for their narrow bandwidth, the use of a stacked patch allows a wider bandwidth. Double layer stacked circular microstrip antennas with different radii have been proposed for use as reflector feeds for satellite communications in the C-band (3.7-4.2 GHz) as well as extended C-band (3.5-4.5 GHz).
