Study of Radiation Characteristics of Slotted Ridged Waveguide Antenna Phased Arrays
Computer simulation of planar phased arrays of air-filled slotted waveguide antennas has been performed for rectangular and single-ridge waveguides to compare their radiation patterns. The simulation has shown that for both arrays radiation pattern exhibits a second-order beam for non-frontal main beam directions. However, this disadvantage is much smaller for ridged array than for rectangular one. Thus, it can be suggested that the use of ridged waveguides can increase the range of angular scanning.
