MULTI-FREQUENCY SHARED ANTENNA

摘要

PROBLEM TO BE SOLVED: To provide a multi-frequency shared antenna in a downsized and simple configuration, capable of realizing excellent antenna characteristics.

SOLUTION: The multi-frequency shared antenna is provided with: a dielectric board 12 placed on a ground plate 11; a high frequency patch 14 formed in the range of a prescribed shape on an upper plane of the dielectric board 12; a low frequency patch 13 formed within the range of including the high frequency patch 14 apart from the range of the prescribed shape on the upper plane of the dielectric board 12 by a gap 15 with a prescribed width from; a high frequency feed point 18 electrically coupled to a prescribed position of the high frequency patch 14; a low frequency feed point 17 electrically coupled to a prescribed position of the low frequency patch 13; two connecting patches 16 or over located at two regions opposed to each other in the gap 15 and sandwiching at least the high frequency patch 14 and for interconnecting the high frequency patch 14 and the low frequency patch 13.
