A wireless signal receiving system, comprising:

• a wireless signal receiving device, comprising:
• an antenna structure, for receiving a wireless reception signal in a plurality of frequency bands;
• a first diplexer, connected to the antenna structure, for splitting the wireless reception signal into a first wireless signal in a low frequency band and a second wireless signal in a high frequency band;
• a first extractor, coupled to the first diplexer, for receiving the first wireless signal and splitting the first wireless signal into a third wireless signal and a fourth wireless signal;
• a second diplexer, coupled to the antenna structure, connected to the first extractor, for combining the wireless reception signal and the third wireless signal into a fifth wireless signal;
• and
• a third diplexer, coupled to the first extractor and the first diplexer, for combining the second wireless signal and the fourth wireless signal into a sixth wireless signal;
