1 results about "Wearable antennas" patented technology

The application relates to the technical field of wearable antennas, in particular to a metal frame smart watch antenna based on a double-feed technology, which comprises a metal frame, a metal ground plate, a parasitic metal, a first feed port, a second feed port, a feed source, a power divider and a phase shifter; the feed source forms two feed paths through the power divider, one of which feeds into the first feed port, and the other feeds into the second feed port through the phase shifter. The antenna can be configured to connect a slot antenna to the first feed port and connect a patch antenna to the second feed port so that the two antennas work simultaneously, or configured to connect the two feed ports to the same patch antenna so that the patch antenna generates a double mode. The scheme is favorable for improving the low-frequency antenna efficiency, improving the bandwidth performance, and realizing double-feed work under the condition of a single excitation source.
