Abstract
Techniques of designing an antenna array with antenna units controlled electronically are described. Each of the antenna units includes a reflector, a driven element and one or more directors. A substrate with conductive material on its surface provided to support the antenna array is designed to be the reflector. The driven element is separated into two halves with each on one side of a non-metal substrate vertically bonded to the conductive substrate. Two driving lines provided to drive the two halves of the driven element are disposed on both sides of the non-metal substrate to minimize possible interactions with other elements of the antenna unit or the antenna array.
