Abstract
A radio frequency device with mechanisms for adjustment of the impedances and frequencies of its antennas comprises a first circuit board, a radio frequency module and a second circuit board. The radio frequency module is disposed on the first circuit board that is disposed on the second circuit board. The radio frequency module comprises an antenna unit, a first frequency tuning element and a radio frequency circuitry. The antenna unit is disposed within a clearance area of the first circuit board, and connected to the radio frequency circuitry via a feeding circuit. The second circuit board comprises a second frequency tuning element that is electrically connected to the antenna unit via a ground circuit and the first frequency tuning element on the first circuit board. Thus, the resonance frequency of the antenna unit can be adjusted according to the first and the second frequency tuning element.
