Abstract
An antenna element comprises one or more directors, a resonator, and a three dimensional ground assembly. Parts of the antenna element are arranged on three metal layers. A top layer has an unconnected metal bar which forms a beam director, a resonator and a top part of the ground assembly. The resonator is an integral piece substantially in the form of a loop connected to a feed line and a feed line terminal ending. The feed line terminal ending serves as the ground plane for the feed line as well as providing impedance matching from the external transceiver circuit to the resonator. The ground assembly includes a top layer ground connected to a plurality of metallized half cylindrical hole channels (or metallized via holes) which connect to a ground terminal in a bottom layer.
