Abstract
An adaptive array antenna for use in a base station according to the CDMA mobile communication system. A number of antenna elements greater than the number of elements (a reference number) which would be required when directional antenna elements each having a beam width which is the same as a sector angle are used to provide a service area having a sector angle which is narrower than the element beam width, or a number of antenna elements each having a beam width broader than the sector angle which is less than the reference number may be used to define a service area.
