Title: Two frequency resonant print dipole antenna
Inventor: EBINE YOSHIO
IPC: H01Q9/16
Filed: 1987-02-06
Abstract: PURPOSE:To align directivity, by mounting a passive element consisting of a metallic conductor at the front of a print dipole antenna. CONSTITUTION:In front of the radiating element of the print dipole antenna, the parasitic deviced consisting of the metallic conductor whose length is less than the 1/2 wavelength of a first resonant frequency and whose width is less than the 1/10 wavelength is mounted. For example, a relation among the radiat ing element 1 of the print dipole antenna, the passive element 2, and the passive element 5 is set as l0>l2>l1. In other words, the l2 is within a range from an l0 to the l1, and the interval between the radiation device 1 of the print dipole antenna and the parasitic device 5 is set constant at 0.06lambdaL. An imped ance characteristic at the first resonant frequency can be improved by decreas ing the width of the passive element 5, and deterioration at a high level is generated by increasing the width larger than omega=0.1lambdaL. In such a way, it is possible almost to align the directivity within a horizontal plane in respective frequency.
