<p>PROBLEM TO BE SOLVED: To provide an antenna module capable of accurately measuring an RF signal input/output from/to a communication unit, and capable of taking measures when the characteristic of an antenna unit is fluctuated or deteriorated after mounted on a communication device.SOLUTION: An RF signal input/output from/to a communication unit 22 is extracted to the outside of an antenna module 2 before dispersion is produced through a matching circuit unit 23 and an antenna unit 21, so as to be accurately measured and inspected by a high-frequency (RF) measuring instrument such as a network analyzer. Also, when the characteristic of the antenna unit 21 is fluctuated or deteriorated after the antenna module is mounted on a communication device 1, it is possible to take measures by connecting an external matching circuit unit 3 or an antenna unit 4 to a signal extraction unit 24.</p> |
