Tent Shaped Phased Array
Abstract
This interim report presents the study results of a tent shaped phased array SHF aircraft antenna for Satellite Communications. The antenna consists of four planar phased arrays and has a low profile streamlined configuration. The tent array provides electrical scanning over a hemisphere and is capable of high power transmission. The design of the array is a trade-off of the key parameters including antenna coverage, gain, aerodynamic impact, high power transmission, and array packaging. The detailed design considerations of these parameters are presented. A design procedure is given to derive an optimum tent array configuration. The design of a 20 dB gain tent array is discussed. This array consists of square waveguide elements, septum polarizers, ferrite and diode phase shifters, a unique feed network, and a microprocessor for array control. The array depth has a significant impact on the aerodynamic effects and array packaging. The development and design of compact array components to reduce the array depth and to provide high power capability is the key factor to the successful application of the tent array. The extension of the 20 dB gain design to a 30 dB gain array is also included. A breadboard planar array, to test the performance of the array and components, and verify the concept of the tent shaped phased array, is being implemented in this effort.
