ANTENNA ELEMENT USED FOR ACTIVE ANTENNA DEVICE AND ACTIVE ANTENNA DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an active antenna device which operates in a wide band.;SOLUTION: An antenna element used for an antenna device as described above comprises: a dielectric substrate having a predetermined thickness; a first linear electrode disposed on one face of the dielectric substrate, and having a longitudinal direction that makes one direction; and a second linear electrode disposed on the other face of the dielectric substrate, and having a longitudinal direction that is the same direction as the longitudinal direction of the first electrode. At least one of the first and second electrodes is composed of a plurality of conductors. The plurality of conductors are electrically connected to each other at their one ends in a face where the plurality conductors are provided. A device which can be used in a wide band as an active antenna device can be arranged by connecting one electrode of the antenna element to a preamplifier, and the other electrode to one of positive and negative power source lines through a resistor.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
