Abstract
Time-domain electromagnetic interference (EMI) measurement systems sample the broadband EMI signal with GHz sampling rates. Direction of incidence resolved EMI measurements are of great interest in open area test sites. We investigate a radially logarithmic periodic circular (LPC) antenna array, capable of steering a beam throughout full 360 degrees of azimuth, for broadband directive sensing of stochastic electromagnetic waves applying time-domain correlation matrix based methods. © 2012 IEEE.
