Patent ID: 7782272

Claim:
An antenna apparatus comprising: an antenna element; and a substrate on which a low noise amplifier is mounted and on which the antenna element is disposed, wherein the substrate comprises: an input unit for inputting an electric signal into the low noise amplifier from an output terminal formed at a lower part of the antenna element; an output unit for outputting the electric signal to a transmission unit connected to a signal processing unit for processing the electric signal from the antenna element; and a signal blocking unit provided between the input unit and the output unit; wherein the antenna element comprises: a cylindrical body formed by a flexible dielectric material film member; and an antenna pattern comprising at least one conducting wire that is formed on a first face of the dielectric material film member; wherein the output unit and the input unit are disposed so as to face each other across the signal blocking unit; and wherein the substrate comprises an upper portion on which the low noise amplifier is disposed and a lower portion on which the output unit and the input unit are disposed so as to be close to each other, and wherein the upper portion is inserted in the cylindrical body and the lower portion is exposed from the cylindrical body.
