AbstractThis paper addresses the system requirements of the C-Band TM antenna that will take the place of the S-Band TM antenna used in applications on munitions and targets that require a quasi-omni directional antenna pattern. For these applications, the C-Band TM effective radiated power (ERP) must be approximately 3 dB higher than the S-Band TM ERP to achieve the same system performance due mainly to weather and environmental differences. From a systems stand-point, this will be a problem for the following reasons: power amplification at higher frequencies is usually less efficient, there is a limit on prime power due to battery capabilities, and a more complex corporate feed at C-Band as compared to S-Band will produce more loss. This means that a more fruitful approach would be to use smart antenna ideas to achieve the required higher ERP as compared to current approaches of using higher power transistors and more battery power. Several smart antenna ideas are introduced in this paper, switchable driven element antenna is described including active amplification at each element.

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.
A Novel Antenna Design for Size Constrained Applications Requiring a Thin Conformal AntennaCirineo, Anthony; David, Rick; Naval Air Warfare Center (International Foundation for Telemetering, 2010-10)This paper will discuss the design of a new antenna element for use on vehicles requiring a thin conformal antenna such as on missiles or targets. The new element employs a partial shorted edge, which reduces the size of the element compared to a traditional microwave patch, while maintaining the impedance bandwidth.
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.
