Abstract
This paper presents a wideband quasi-Yagi antenna with a driven element in the form of tapered strip. The antenna is designed to be part of a circular array for a microwave imaging system. The feeding structure of the antenna includes a balun that is formed using a pair of microstrip to slotline transitions. The simulated results of the proposed antenna indicate more than 73% fractional bandwidth with more than 10 dB return loss and about 3 dBi to 5 dBi gain.
