Paper Abstract

Recent topics on ESPAR (Electronically Steerable Parasitic Array Radiator) antennas, which we have proposed as an adaptive antenna for mobile user terminals, are described. The measurement characteristics of a 2.4 GHz 7-element ESPAR antenna are given along with its design criteria. Experimental work on an ad hoc network with 2.4 GHz ESPAR antennas is now proceeding and preliminary results are given. The design and fabrication of a beam-steerable 60 GHz planar microstrip antenna for the TV receiver of an indoor multi-channel video transmission system are presented as another example of user terminal applications. Beam steering is realized by varactor phase shifters at low cost.
