CELLULAR base stations require a highly directive antenna with proper
beam shaping and beam squinting in order to provide effective coverage
of the cell area. An antenna system satisfying these requirements has
been realized by applying the method of moments in conjunction with i
mage theory to design an array of flat dipole elements placed above a
ground plane. A fabricated collinearr array designed with this method
provides operation across the 800-to-960-MHz bandwidth.
