Abstract: This paper proposes the estimation of mean electrical phase center (MEPC) in different GNSS patch antennas. In the past, edge diffraction theory is quite complex and difficult to find the exact location of antenna phase center. In this work, an improved and determine the mean electrical phase center of horn and patch antenna in Cartesian coordinates. The Patch antenna can provide higher accuracy in GNSS positioning compare to horn antenna. The experimental results show that the patch and horn antenna phase center variation with change in observation angle and frequency are presented.
