Dipole antennas with impedance matching elements in the near-field
Abstract
It have been researched theoretically and by computer simulation the possibility of tuning a resonant frequency and band with minimal VSWR of symmetric dipole antennas of finite length placed parallel to the ideally conducting flat screen. It is reached by placing in the near zone between dipole and screen of metal pin and/or disk. Experimental study has been made as well. It is shown that the most broadband case is implemented by placing both elements – a short pin near to the dipole and disk close to the screen. Theoretically and experimentally proved that the used matching elements practically do not affect to the directivity pattern of given dipole antennas.
