Dual-band compact-size antenna array for angle of arrival estimation
Authors/Creators
Description
A dual-band compact-size ring antenna array is integrated with a proposed angle of arrival (AOA) algorithm to estimate directions of arrival sources. The impact of mutual coupling on the direction estimation accuracy is investigated based on the computed coupling matrices for both spectrum frequency bands. The mathematical model of direction of arrival (DOA) is illustrated and an appropriate decoupling
method is integrated to eliminate the mutual coupling effects. A
MATLAB code is developed to simulate various experimental
scenarios. The results before and after compensation of coupling matrix are compared and discussed for several test examples.
