Claim Text:
1. A communication system, comprising: a first antenna; a second antenna; a first transceiver; a second transceiver, wherein each of the first transceiver and the second transceiver is a combined element with functions of both signal transmission and reception; and a phase and power distribution transform circuit, coupled between the first antenna, the second antenna, the first transceiver, and the second transceiver; wherein the phase and power distribution transform circuit is configured to adjust phase and power of each signal from the first antenna, the second antenna, the first transceiver, and/or the second transceiver, thereby improving communication quality of the communication system, wherein the phase and power distribution transform circuit at least comprises a first coupler and a second coupler for combining or dividing signals, wherein the first coupler has a first terminal coupled to the first antenna, a second terminal, and a third terminal, and wherein the second coupler has a first terminal coupled to the second antenna, a second terminal, and a third terminal, and wherein the first coupler and the second coupler are both electrically connected to the first transceiver and the second transceiver.
