A technique for elimination of reflected rays from antenna measurements performed in echoic environment
The paper describes a technique for analyzing antenna measurements and removing reflected components present in measurements performed in echoic environments. The method is based on digital signal processing methods, and frequency-domain measurements are used to design a discrete-time, finite impulse response digital filter using least-squares methods. The frequency response of the filter is equal to the transmission coefficient measurements performed in an anechoic chamber. In order to verify the method, processed measurements of mutual coupling between stacked patch antennas were compared to the computer simulations of anechoic response, and a very close agreement was achieved.
