Electronic device, communication device, and antenna gain enhancement method for a detachable wireless communication module

A communication device, comprising:

• a detachable wireless communication module having a main antenna;
• and
• an electronic device, comprising:
• a socket disposed on the electronic device, wherein the socket comprises an accommodating portion for accommodating the detachable wireless communication module inserted from the outside;
• and
• a supplementary antenna disposed in the electronic device, wherein when the detachable wireless communication module is completely inserted into the accommodating portion, a main antenna of the detachable wireless communication module and the supplementary antenna become electromagnetically coupled;
• and
• wherein when the detachable wireless communication module is completely inserted into the accommodating portion, the communication device transmits/receives wireless signals using the main antenna together with the supplementary antenna;
• wherein the socket further comprises:
• a first contact point, wherein when the detachable wireless communication module is completely inserted into the accommodating portion, the detachable wireless communication module touches the first contact point so that the main antenna keeps a predetermined distance from the supplementary antenna for realizing non-contact electromagnetic coupling.

An antenna gain enhancement method for a detachable wireless communication module, comprising:

• disposing a socket on an electronic device, wherein the socket comprises an accommodating portion for accommodating the detachable wireless communication module inserted from the outside;
• disposing a supplementary antenna in the electronic device;
• and
• inserting the detachable wireless communication module into the accommodating portion so that a main antenna of the detachable wireless communication module and the supplementary antenna jointly become electromagnetically coupled, wherein when the detachable wireless communication module is completely inserted into the accommodating portion, the detachable wireless communication module transmits/receives wireless signals using the main antenna together with the supplementary antenna;
• wherein the electromagnetic coupling further comprises:
• disposing a first contact point on the socket;
• and
• completely inserting the detachable wireless communication module into the accommodating portion to touch the first contact point of the socket so that the main antenna keeps a predetermined distance from the supplementary antenna for non-contact electromagnetic coupling.
