An apparatus for wireless data communications is provided. The apparatus comprises a substrate, a microstrip line of a quarter-wavelength, a contact pad, an impedance transformer of the quarter-wavelength, a ground plane, a loop antenna of the quarter-wavelength and a monopole antenna of the quarter-wavelength. The substrate has a first surface and a second surface opposite to the first surface. The microstrip line, the contact pad, the impedance transformer are formed on the first surface of the substrate. Both the ground plane and the loop antenna are formed on the second surface. The loop antenna is configured with one end connected to the ground plane, and another end overlapped with the microstrip line and spaced from the ground plane. The monopole antenna is attached to the contact pad.
