MIC Radiating Elements and Arrays

Abstract
This paper describes radiating elements using microelectronic integrated circuits (MIC) techniques. A method of investigation has been developped, using liquid crystals which permits to study matching and radiating parameters of tested elements. Performances of these elements are compared to performances of classic elements (i.e. horn), taking into account either electrical characteristics, either size. Examples of multielement antennas are given : log periodic array, multi slot array. The advantages of these antennas are discussed and the integration of MIC radiating elements in a more complex circuit is illustrated by a X band receiver and a X band radar head.
