Development of UHF and L Band Ground Sectoral Antenna.

• Antennas should work in UHF band and L band.
• The antennas gain should be not less than 10 dBi in case of UHF antenna and the gain for L band antennas should be not less than 12 dBi.
• The antenna Half Power beam width in Azimuth should be not less than 90 degrees. 
• The antennas should be vertically polarized.
• The antenna shall be designed to withstand various environmental conditions, including temperature, humidity and wind stress load as per JSSS5555 or MIL-810-F/G.

Future Expectation from the prototype / Technology developed

It is expected to achieve optimum data communication ranges from the developed antennae for the data link systems under development at HAL.
