Abstract: An X-Band microstrip antenna for use on a fourteen inch diameter projectile to transmit telemetry data. The X-Band microstrip antenna is configured to wrap around the projectile's body without interfering with the aerodynamic design of the projectile. The X-Band microstrip antenna operates at 7900 to 8100 MHz telemetry frequency band. Sixteen microstrip antenna elements equally spaced around the projectile provide for linear polarization and a quasi-omni directional radiation pattern.

Abstract: A method for fine tuning a microstrip antenna which has eight tuning tabs for tuning the antenna frequency of the microstrip antenna. The antenna is designed to operate around 430 MHz with a tuning step size of approximately 1.5 MHz. The method utilizes the eight tuning tabs to tune the antenna from a center frequency of 427.2 MHz when all eight tuning tabs are connected to the cooper radiating or antenna element of the antenna incrementally to a center frequency of 439.3768 MHz when the eight tuning tabs are disconnected from the cooper antenna element.

Abstract: A near field probe for testing installed components of an electromagnetic radiating system on a missile. The probe design comprises a diode antenna with a balun. The probe utilizes a dual diode arrangement which provides approximately twice the output voltage as the previous probe. The probe may then be placed further away from the radiating system under test.

Abstract: A TM microstrip antenna which having a pair of mode suppression slots for transmitting telemetry data to an external source, which is adapted for use in a small area on a weapons system such as a missile. The mode suppression slots reduce noise from the TM microstrip antenna at the GPS L-1 band providing increased isolation between the TM microstrip antenna and a GPS receiving antenna mounted in proximity to the TM microstrip antenna.

Abstract: A reduced size GPS microstrip antenna which has an annular slot, receives GPS data from an external source and which is adapted for use in a small area on a weapons system such as a missile. The microstrip antenna is square shaped with angled notches at opposite corners of the antenna.

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.

Abstract: A GPS microstrip antenna designed to receive satellite provided GPS position for use by a nine inch diameter projectile. The GPS microstrip antenna is configured to wrap around the projectile's body without interfering with the aerodynamic design of the projectile. The GPS microstrip antenna operates at 1.575 GHz with a bandwidth of ±10 MHz. Eight microstrip antenna elements equally spaced around the projectile provide for circular polarization and a quasi-omni directional radiation pattern.

Abstract: A GPS conical shaped microstrip antenna array which receives GPS data and which is adapted for use on weapons systems such as a missile or smart bomb. The microstrip antenna array has a center frequency of 1.575 GHZ, a frequency bandwidth of twenty megahertz and provides for right hand circular polarization. The microstrip antenna includes a four aligned copper antenna elements which have a square shape, and a copper etched feed network which provides for a signal phase shift of ninety degrees resulting in right hand circular polarization of each of the four aligned antenna elements.

Abstract: A reduced size microstrip antenna which receives GPS data and which is adapted for use on small diameter weapons systems such as a missile or smart bomb. The microstrip antenna has a center frequency of 1.575 GHz, a frequency bandwidth of twenty megahertz and provides for right hand circular polarization. The microstrip antenna includes a pair of quarter-wavelength antennas which have a rectangular shape and are rotated ninety degrees from one another, and a copper etched feed network which provides for a signal phase shift of ninety degrees.
