AbstractA pattern-reconfigurable, low-profile, efficient, electrically small, near-field resonant parasitic (NFRP), Huygens source antenna is presented. The design incorporates both electric and magnetic NFRP elements. The electric ones are made reconfigurable by the inclusion of a set of p-i-n diodes. By arranging these electric and magnetic NFRP elements properly, a set of three Huygens sources are attained, each covering a 120 degrees sector. Pattern reconfigurability is obtained by switching the diodes on or off; it encompasses the entire 360 degrees azimuth range. A prototype was fabricated and tested. The numerical and experimental studies are in good agreement. The experimental results indicate that in each of its instantaneous states at f(0) = 1.564 GHz, the antenna provides uniform peak realized gains, front-toback ratios, and radiation efficiencies, respectively, as high as 3.55 dBi, 17.5 dB, and 84.9%, even though it is electrically small: ka = 0.92, and low profile: 0.05 lambda(0).

ANTENNA CONTROL FOR TT&C ANTENNA SYSTEMSKaiser, Julius A.; Herold, Fredrick W.; Fredrick Herold and Associates, Inc. (International Foundation for Telemetering, 2000-10)A thinned array sensor system develops error voltages for steering dish antennas from signals arriving over a broad range of angles, thereby eliminating need for a priori knowledge of signal location.
MICROPROCESSOR BASED ANTENNA CONTROLLER DEMONSTRATES FLEXIBLE REMOTE CONTROL OF TELEMETRY ANTENNA SYSTEMSDebrunner, K.E.; Electro Magnetic Processes, Inc. (International Foundation for Telemetering, 1983-10)The remote control capabilities of a smart antenna control unit are briefly described. Examples of how these capabilities can be used to improve range coverage and operation are given, and various network configurations are illustrated. Examples of the command language for this antenna controller are also given to illustrate the flexibility of control available and the ease of use of the interface language.
DESIGN AND APPLICATION OF ANTENNA COUPLERS FOR CERTIFICATION OF AIRBORNE INSTRUMENTATION ANTENNASKujiraoka, Scott R.; Davis, Rick; Naval Air Warfare Center Weapons Division (International Foundation for Telemetering, 1999-10)Instrumentation antennas installed on missiles and airborne targets are required to be tested and certified prior to flight. The antenna coupler is a means of certifying that the antenna is in proper working condition prior to deployment, as damage to the antennas may have occurred during transportation or installation. This coupler also provides a low cost means to evaluate and monitor the antenna throughout the various stages of design and assembly. These antennas can contain arrays for telemetry, beacon tracking, global positioning systems and flight termination. A failure by any one of these arrays could result in the loss of data or improper operation of the flight vehicle. Description of the design and function of antenna couplers will be discussed.
