            Abstract : 
A modular high-gain antenna, installed at a relatively low height, has been shown to provide link budget improvement over a large part of the serviced cell, including near the cell border which shows the potential for larger site separations. Signal strength below the relatively narrow main beam is maintained by using null-filling.
