Effects of Ground Constituent Parameters on Array Mutual Coupling for DOA Estimation

Effects of Ground Constituent Parameters on Array Mutual Coupling for DOA Estimation

Effects of ground constituent parameters on the mutual coupling (MC) of monopole antenna array are investigated. This work augments an existing MC compensation technique for ground-based antennas and proposes reduction in mutual coupling for antennas over finite ground as compared to the perfect gro...
