“…Due to these concerns, previous predictive modeling efforts in this area were almost entirely limited to the use of full wave 3-D numerical tools based on techniques such as the finite element or difference methods [3]- [7]. Numerical electromagnetic methods usually are very time consuming for complex structures.…”

Abstract-A novel technique is presented for the accurate, rapid, high frequency, predictive modeling of parallel plate capacitors with gridded plates manufactured in a multilayer low temperature cofired ceramic (LTCC) process. The method is empirical in nature and is based on the concept of incrementally constructing the model for a structure from well characterized individual building blocks. Building blocks are characterized by the use of test structures and measurements, and are modeled using passive lumped circuit elements. This method is applied to the predictive modeling of deeply embedded gridded parallel plate capacitor structures. The procedure has been experimentally verified, with accurate predictions of behavior obtained up to the second self resonance for large area gridded parallel plate capacitors. Since lumped element circuits are generated by this method, structure prediction speed is determined by circuit size and simulator small signal analysis time. The method is versatile and is well suited for circuit design applications.

Reduced-height rectangular crossed waveguide cross-slot directional coupler has been designed at W band (75 GHz-110GHz) with computer aided design approach and experimentally verified. The coupler has been simulated and optimized with 3D full wave electromagnetic field simulator HFSS. Coupling of 10.5 dB is achieved with good directivity within a bandwidth of more than 10%. The experimental result closely matches with the simulation.

A systematic synthesis procedure for ridge waveguide branch line couplers in both E-plane and H-plane configurations is presented. Ridge waveguides are chosen to benefit from their wide mono-mode band and compact size compared to rectangular waveguides. Equivalent circuit parameters are used to synthesize the coupler sections. Rigorous mode matching method is used for full-wave analysis and optimization of the couplers. Ridge couplers both in empty waveguide and Low Temperature Co-fired Ceramic ''LTCC'' technology are designed using the proposed method and the design is verified with another numerical method. A prototype is built and its response is measured to verify the approach.
