MERIDEN, Conn. -- A breakthrough in microwave antenna design by wireless technology group, Radio Frequency Systems (RFS), provides an exciting new solution for point-to-point communications in the 11-GHz band. The RFS SlimLine SU3-107FC microwave antenna is the first antenna on the market--smaller than four feet in size--to meet the stringent FCC part 101 Category A requirements in this band.

RFS Area Product Manager, Asad Zoberi, said that the feed system of the three-foot SU3-107FC has been re-designed to ensure the antenna complies with FCC part 101 Category A. “Until now, the only way to meet the FCC Category A requirements in the 11-GHz band was to use a four-foot antenna,” he said. “But this is often an overkill from the required system gain perspective. Furthermore, end users are constantly challenged by zoning and permit applications--they want antenna solutions that are smaller and more lightweight to minimize the tower loading. This three-foot antenna is a real breakthrough.”

According to Zoberi, the 11-GHz band (10.7 to 11.7 GHz) is an ideal option for point-to-point communications, with links typically spanning five to 20 miles. Its 40-MHz channels allow high-capacity data transfer (3 DS3s or OC3)--a significant improvement on the capacity-limited 10-GHz band, where data throughput of the 5-MHz channels is restricted to 16 DS1s. Furthermore, the 11-GHz band does not suffer as severe an effect of rain attenuation as the 18-GHz band.

“Despite these attributes, the need for a four-foot antenna to meet the FCC Category A regulations had limited the use of 11-GHz band,” said Zoberi. “But this three-foot antenna is going to change all that. It will provide a new tool for the 11-GHz band to be utilized more efficiently.”
