Abstract

This paper deals with the design of a Frequency Selective Surface (FSS) used as a sub reflector in a satellite. The FSS is designed by cutting slots in the square patch keeping same periodicity throughout. Frequency-selective surfaces are spatial filters which when incorporated as either flat or curved sub reflectors into a reflector antenna allows it to operate at a number of different frequency bands. This designed FSS structure has a wide stop band from 3.70GHz to 6.23GHz with percentage bandwidth of 51. Size reduction up to 83% is also achieved in this paper. Theoretical investigations have been done by Ansoft® designer software.
