Problems solved by technology

[0002] Today's wireless products, such as wireless network base stations, need to use 11b / g and 11a antennas in IC modules with different frequency bands due to product requirements to meet system product requirements, so at least two antennas (one for each frequency band) must be provided. Need at least one) to meet product requirements, but this will cause difficulties in product appearance and size design

Abstract

The invention provides a dual-band single antenna comprising a first radiator, a second radiator, a first signal feed-in unit and a second signal feed-in unit. The first signal feed-in unit is electrically connected with the first radiator, the second signal feed-in unit is electrically connected with the second radiator, and the first radiator, and the second radiator, the first signal feed-in unit and the second signal feed-in unit are all arranged in the dual-band single antenna. Accordingly, the antenna number can be reduced to decrease product development cost and signal transmission efficacy is better.

Description

technical field [0001] The invention relates to a dual-frequency antenna unit, in particular to a dual-frequency antenna unit in which antennas of different frequency bands are arranged in the same dual-frequency antenna unit and has good signal transmission performance. Background technique [0002] Today's wireless products, such as wireless network base stations, need to use 11b / g and 11a antennas in IC modules with different frequency bands due to product requirements to meet system product requirements, so at least two antennas (one for each frequency band) must be provided. Need at least one) to meet product requirements, but this will cause difficulties in product appearance and size design. [0003] Therefore, how to develop a dual-band antenna unit, which can reduce the number of antennas to reduce product development costs, and has good signal transmission performance, will be actively discussed in the present invention. Contents of the invention [0004] The pr...
