ABSTRACT:
A TM microstrip antenna designed to transmit telemetry data for use by a nine 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 2.25 GHz with a bandwidth of ±10 MHz. Eight microstrip antenna elements equally spaced around the projectile provide for linear polarization and a quasi-omni directional radiation pattern.
