ANTENNA GAIN SPECIFYING DEVICE AND RADIO COMMUNICATION DEVICE

Title:

ANTENNA GAIN SPECIFYING DEVICE AND RADIO COMMUNICATION DEVICE

Document Type and Number:

Japanese Patent JP2004325239

Kind Code:

A

Abstract:

To specify an antenna gain even when an antenna having an optional antenna gain is connected.

This radio communication device 10 includes the first connector 26 for connecting the first antenna 30 having the optional antenna gain, the second antenna 24 having a known antenna gain, a receiving circuit 14 for receiving a radio wave, and a control circuit 12 for specifying the relative antenna gain of the first antenna 30 to the second antenna 24 by using the intensity of the first radio wave received by the receiving circuit 14 by using the first antenna 30 connected to the first connector 26 and the intensity of the second radio wave received by the receiving circuit 14 by using the second antenna 24, and controlling the receiving circuit 14 based on the intensity of the third radio wave determined by correcting the intensity of the first radio wave based on the relative antenna gain.
