MULTI-BAND ANTENNA AND BOARD FOR THE SAME

摘要

A multi-band antenna and a substrate for the same are provided to minimize interference between antenna elements regardless of a distance between the antenna elements by forming an isolating unit between the antenna elements. A multi-band antenna includes first and second antenna units and an isolating unit(170). The first antenna unit has a first feed element(132) connected to a feed unit of the antenna and a first antenna element electrically connected to the first feed element to resonate in a first frequency band. The second antenna unit has a second feed element(152) connected to the feed unit of the antenna and a second antenna element electrically connected to the second feed element to resonate in a second frequency band. The isolating unit is formed between the first and second feed elements, made of conductive material, and electrically connected to a ground plane.
