Low cost steerable active array element design
Abstract
Investigations devoted to the development of novel techniques for the simplification and hence reduction in cost of active arrays are considered, taking into account the design of a simple element which performs both functions of transmit and receive with usage of as many components as possible in both functions. Active array element basic principles are considered along with phase-locked loop locking characteristics. A description is presented of tests conducted on a single element and a small array. The single element was constructed using a 300 mW pulsed, varactor-tuned Gunn oscillator. A possible drawback to the considered circuit is that on transmission, external signals entering the loop via the element aperture may affect the locking conditions and such signals could occur from mutual coupling between elements.
