AS-49090 Single Layer Microstrip Patch Antenna

It is fed by a perpendicular probe. This antenna is inherently-circularly polarized. It has the advantage of low height, high efficiency, and full hemispherical coverage. The materials used in the construction of the antenna were chosen to minimize the effects of the extreme environments. Its baseplate is curved to mount to a 100-inch radius vehicle. The baseplate can be modified to suit the mounting requirements of a particular vehicle. An aerospace test coupler, P/N 750606, is available for this antenna. This enables open loop testing while the vehicle is on the launch pad.

Features:

  • Space Qualified
  • Temperature Extremes
  • High Vibration Levels
  • Ideal Telemetry Antenna
  • Circular Polarization
