            Abstract : 
The feasibility of printed antennas which meet all the criteria for satellite communications antennas is considered. These criteria are a bandwidth greater than 20% for a VSWR of less than 1.5, crosspolar level lower than -30 dB over 20 degrees solid angle, and gain better than 8 dB throughout the bandwidth.
