Abstract

The invention provides a loop type coupling antenna, which includes: a feed-in wire, a coupling conductor, a first coupling part, a second coupling part, a second conductor and a ground surface, one end of the coupling conductor belongs to the first coupling part, another end belongs to the second coupling part; the feed-in wire connects with the first coupling part for providing a feed-in signal to the first coupling part; the feed-in signal couples to the second coupling part through the coupling conductor; one end of the second conductor connects with the second coupling part, another end connects with the ground surface that conduct signal of the second coupling part to the ground surface by using the second conductor. Impedance match can be adjusted efficiently by using the first coupling part, and antenna operation frequency width can be increased. The second coupling part and the second conductor reduce resonant frequency, and shorten wavelength of resonant path center frequency.
