<P>PROBLEM TO BE SOLVED: To provide a receiving system capable of preventing a drop in the receiving sensitivity of a receiving means. <P>SOLUTION: The receiving system detects an object which exists within the range predetermined by an antenna 2, and prevents the antenna 2 from picking up radio waves by locating an infrared sensor 35 capable of detecting an infrared radiation emitted and reflected by a human body around the antenna 2. When the receiving system compares a signal power Pant representing a field intensity of the radio waves picked up by the antenna 2 with the threshold power Pth, the threshold power Pth is greater, and this object has been detected by the infrared sensor 35; the receiving system broadcasts a warning information to users of a mobile terminal 1 using at least either one among a warning indicator 23, a warning beep generator 24, and a warning vibrator 25, and prompts this object to be moved out of the range predetermined around the antenna 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
