ABSTRACT:
A TM microstrip antenna designed to transmit telemetry data for use by a fourteen inch diameter projectile. The microstrip antenna is configured to wrap around the projectile's body without interfering with the aerodynamic design of the projectile. The TM microstrip antenna operates at the 2200 to 2300 MHz TM frequency band. Eight microstrip antenna elements equally spaced around the projectile provide for linear polarization and a quasi-omni directional radiation pattern.
