Phase measurement DOA detection is commonly used nowadays. However, the traditional approach are based on conventional mixer architecture or expensive direct conversion devices which has high complexity and costly while comprising robustness. Therefore a new interferometer DOA detection system based on six-port network has been lately investigated and is showing several advantages in respect to traditional...
Ground Penetrating Radar (GPR) is one of the non-destructive methods which employ electromagnetic wave to map the buried features in the ground or man-made structures. Basically, GPR consist three main components which are antennas, control unit and display. In this paper, wideband slotted antenna for microwave imaging system in Ground Penetrating Radar (GPR) applications is presented. The design...
The design of a novel wideband six‐port network on a single layer microstrip substrate is presented.Two different configurations of the single‐layer six‐port networks, one conventional and the other nonconventional, are designed, fabricated, and measured. The six‐port network based on the conventional configuration is formed by one Wilkinson divider and three couplers, with one unused port terminated...
