Abstract:

This thesis describes a fin-line 180 degree hybrid magic-tee that is suitable for use in monopulse radar antennas at microwave and millimeter-wave frequencies. The three-dimensional junction of a waveguide magic-tee is replaced with fin-line slots, coupled fin-line slots and microstrip lines mounted in a waveguide fixture. The planar geometry on the substrate provides significant reduction in size and eliminates the waveguide ratrace that is associated with conventional hybrids. Ports one and two are flared into fin-line horns to produce a fin-line monopulse system. Suggestions for further development of the fin-line magic-tee and monopulse system are presented. Keywords include Millimeter wave comparator Fin-line comparator Fin-line magic-tee Monopulse comparator Monopulse antenna and Monopulse radar.
