EMC - Above 20 GHz, An Introduction

This paper discusses the characteristics of the Extremely High Frequency (EHF) spectrum and the equipment operating within the spectrum. These characteristics are related to the unique nature and extent of the Electromagnetic Compatibility (EMC ) analysis and Electromagnetic Interference (EMI) Control problems to be expected. Achieving EMC above 20 GHz is becoming increasingly important to the users of the EHF spectrum and the EMC community. Continued development and exploitation of the lower microwave region is resulting in spectral crowding which, in turn, will require greater utilization and exploitation of the much more open spectrum available at EHF. Consequently, the EMC community must plan for the control and orderly development of equipment for the utilization of the EHF spectrum.
