A Quagi antenna is a variation on the venerable Yagi-Uda. Quagi antenna is designed using 4NEC2 tool. Antenna is designed and analysed its performance by varying elements spacing. A Quagi antenna is merely one of the most interesting amateur antenna designs to come down the pike in recent years. It’s easy and noncritical construction, cheap as well as simple matching of the feed line to the driven element, makes Quagi antenna an attractive alternative to both Quad and Yagi-Uda arrays. As the quad loops make an excellent driven element and reflectors, rods seem to be superior directors, this made us to choose Quagi antenna for designing.
