%0 Journal Article %T Simple Modelling Approach for Via-Hole Characterization on Silicon Substrate at Ka-Band %A K. Singh %A K. Nagachenchaiah %J Microwave Review %D 2011 %I Society for Microwave Technique, Technologies and Systems, Serbia and Montenegro IEEE MTT-S Chapter %X This work presents a simple model of via-hole using electromagnetic field solver. Equivalent model parameters on Si are found out at Ka-band. Proposed single via-hole model has been compared with theoretical published data. The effect of via-hole radius and substrate height at Ka-band frequencies has been studied. Further, S-parameter analysis and comparison for multiple vias at two different frequency bands is carried out. %K Via-hole %K Radio-frequency %K High resistivity substrate %K Conductor backed- CPW (CB-CPW) %K Grounding %U http://www.mtt-serbia.org.rs/microwave_review/pdf/Vol17No1-05-KSingh.pdf
