Monopole antenna provided with first rectangular through hole

摘要: The invention discloses a monopole antenna provided with first rectangular through hole. the hole comprises two oscillator units in longitudinal symmetry. Each of triangular radiation piece, is formed bottom edge piece extends to form transition plate perpendicular edge, and free end second parallel piece. By means good structural design, front-to-rear ratio characteristics are achieved continuous tests parameter adjustment, lowest frequency point single unit larger than 30dB, average band 32dB; furthermore, high gain obtained, 9.37dBi 9.8dBi according measured data directional diagram.
