Grounded Frequency Selective Surface Array as Millimeter Wave Beam Splitter

This paper presents the design, construction and testing of grounded Frequency Selective Surface (FSS) array as millimeter wave beam splitter. The phase dependence on slot length of grounded FSS demonstrates that the reflection phase of coherent mm-wave can be altered by using FSS array with different slot lengths. A beam splitter was designed with slot FSS array where the slot length is the main design parameter used to optimize the phase properties of the array. We simulated the FSSs with commercial CST Microwave studio software, fabricated them with etching technique and characterized with a free space MVNA and BWO with motorized detector setup.
