Antenna and Method for Producing the Same

摘要

An antenna of the present invention includes a laminate body including a conductor core, an insulator layer, and a conductor pattern. The conductor pattern is a conductor layer formed of a conducting body disposed on a radially outer side of the insulator layer. The conductor core and the conductor pattern are connected to each other in such a manner that a current is made to flow in a direction from the conductor core to the conductor pattern or in a direction opposite thereto so as to coincide with a power supply direction.

主权项

1. An antenna comprising a laminate body configured so that a current is made to flow therethrough, thereby transmitting and receiving radio waves,
the laminate body comprising: a conductor core formed of an elongated conducting body; an insulator layer formed of an insulating body disposed on a radially outer side of the conductor core; and a conductor pattern disposed on a radially outer side of the insulator layer and formed of a conducting body having such a shape that a power supply direction in which the current flows becomes a direction from one end side to an other end side in an axial direction or a direction opposite thereto, wherein the conductor pattern is a conductor layer formed of a conducting body disposed on the radially outer side of the insulator layer, and wherein the conductor core and the conductor pattern are connected to each other in such a manner that a current is made to flow in a direction from the conductor core to the conductor pattern or in a direction opposite thereto so as to allow its power supply direction to coincide with the aforesaid direction.
