Abstract: A loop antenna includes a printed circuit board (PCB), a first antenna structure and a second antenna structure. The PCB includes a first surface and a second surface relative to the first surface, and the PCB includes a clear region and a ground region, wherein the clear region is adjacent to the ground region. The first antenna structure is disposed in the clear region at the first surface. The first antenna structure includes a feed structure and a first ground end. The feed structure is coupled to a power feed end which is disposed in the ground region. The first ground end is coupled to the ground region. The second antenna structure is disposed relative to the first antenna structure at the second surface. The second antenna structure includes a second ground end. The second ground end is coupled to the ground region.

Abstract: A wireless communication module includes a first circuit board, a second circuit board, a chip antenna, an electrical connector and an electrical conductive member. The first circuit board and the second circuit board are electrically connected to each other and arranged in parallel spaced relationship. The chip antenna is located on the first circuit board. The electrical connector is located on the second circuit board and between the first and second circuit boards. The electrical conductive member extends from a metal housing of the electrical connector and has at least a radiation aid portion and a shielding portion. The electrical conductive member and the first circuit board collectively define a hollow space, wherein the electrical connector and the electrical conductive member are electrically connected to the chip antenna to serve as an electromagnetic radiation aid member for the chip antenna.
