Linearly polarized logarithmic periodic printed circuit board based dipole antenna, has dummy line mounted opposite to external feeder in axis symmetric manner to longitudinal axis of antenna and/or parallel to external feeder
Linearly polarized logarithmic periodic printed circuit board based dipole antenna, has dummy line mounted opposite to external feeder in axis symmetric manner to longitudinal axis of antenna and/or parallel to external feeder
The antenna has a dummy line (B) approximately provided outside an external feeder (A) of the antenna and soldered up to a feed point of the antenna. The dummy line is mounted opposite to the external feeder in an axis symmetric manner to a longitudinal axis of the antenna and/or parallel to the external feeder. Ring ferrites are mounted around a pair of external feeder and dummy lines between a largest resonator and a connector plug to a measuring device.
