Title:
COMBINATION ANTENNA WITH MANY FEEDER POINTS
Document Type and Number:
Japanese Patent JP2007274742
Kind Code:
A
Abstract:
To provide a combination antenna with a common structure for combining a first electromagnetic radiation element and a second electromagnetic radiation element.
The first electromagnetic radiation element 310 and the second electromagnetic radiation element 320 are tuned to be independent of each other and to simultaneously operate at first and second frequency bands, respectively. The common structure including a common antenna structure, a common mounting structure and a common grounding structure, saves space as compared to a combined space occupied by the first electromagnetic radiation element and the second electromagnetic radiation element, which are mounted separately as independent antennas.
