ANTENNA AND MIMO ANTENNA HAVING THE DUAL-POLARIZED ANTENNA

摘要

The present invention relates to an antenna. The antenna comprises a dielectric substrate, a first metal sheet and a second metal sheet respectively attached to two opposite surfaces of the dielectric substrate, a first feeder cable windingly arranged on the first metal sheet, and a second feeder cable windingly arranged on the second metal sheet. The first feeder cable and the second feeder cable respectively are fed into the first metal sheet and the second metal sheet via coupling. The first metal sheet and the second metal sheet respectively have engraved thereon a first microgroove structure and a second microgroove structure. The first feeder cable and the second feeder cable are electrically connected. On the basis of the antenna of the present invention, the dielectric substrate has arranged on both surfaces thereof the metal sheets, and fully utilizes the spatial area of the antenna; this condition allows the antenna to operate at a lowered operating frequency, while at the same time to meet the requirements of antenna miniaturization, of lowered operating frequency, and of broadband multimode. The present invention also relates to an MIMO antenna having the antenna.
