Design of Compact Cross-Fed Three-Dimensional Slot-Loaded Antenna and Its Application in Wideband Head Imaging System

Abstract

Microwave head imaging systems require compact wideband antennas with directional radiation. To realize the antenna miniaturization, the halving technique based on image theory has been used. However, it causes a tilt in the main-beam direction. This letter demonstrates that the side feeding technique can be used to cross-feed the halved antennas with the… (More)
