Coupling assistance device and RFID communication system

An RFID communication system comprising:

• a first device that includes a first antenna;
• a second device that includes a second antenna;
• and
• a coupling assistance device configured to communicatively couple to the first antenna and the second antenna, the coupling assistance device including:
• a base that includes a first principal surface;
• and
• a planar antenna disposed at the base,
• wherein the first principal surface of the base includes:
• a first region configured to have the first device placed thereon, and
• a second region configured to have the second device placed thereon,
• wherein the first region and the second region are positioned at a distance relative to each other such that, when the first antenna is placed adjacent to the first region and the second antenna is placed adjacent to the second region, the first device and the second device are both simultaneously positioned on the first principal surface of the base, and
• wherein the planar antenna extends from the first region of the base to the second region of the base, and is communicatively coupled to the first antenna in the first region and the second antenna in the second region when the first and second devices are placed on the first and second regions, respectively.
