Abstract: A microstrip antenna configured to wrap around approximately 270 degrees a projectile's body without interfering with the aerodynamic design of the projectile. The microstrip antenna has two identical grounded quarter wavelength microstrip antenna elements positioned around the circumference of the projectile's body. The antenna has an operating frequency of 425 MHz ±375 KHz, a maximum diameter of ten inches and a maximum length of nine inches. The microstrip antenna outputs a pair of equal amplitude flight termination signals and produces a quasi omni-directional radiation pattern with linear polarization.

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.

The antenna 12 fabricated from high dielectric constant material to reduce the size of the antenna which has a diameter of 1.364 inches.

Abstract: A GPS microstrip antenna designed to receive satellite provided GPS position information for use by a fourteen 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 right hand circular polarization and a quasi-omni directional radiation pattern.

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.

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 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 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 Test Chamber for testing a frequency response of a Low Band Antenna Array output by injecting an RF test signal into the interior of the test chamber. The test chamber comprises a rectangular shaped steel enclosure having a lid. A microwave absorptive foam is affixed to the interior walls and base of the enclosure. The lid for the enclosure includes an opening and a pair of alignment pins for positioning the array's monopole antennas within the interior of the test chamber. A probe is located in one corner of the test chamber to provide the RF test signal to the array's monopole antennas.

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.
