摘要
A printed circuit board (PCB)-printed antenna for a radio frequency (RF) front end with an antenna port for a predefined operating frequency band. A radiating element with a first branch defined by a first set of dimensions corresponding to a minimum frequency and a second branch defined by a second set of dimensions corresponding to a maximum frequency is fixed to a PCB substrate. A third branch is defined by a third set of dimensions corresponding to a middle frequency in various embodiments. A feed line is electrically connected to the radiating element and defines a feed port that is connectable to the antenna port. A ground line is electrically connected to the radiating element and defines a ground port. The first branch defines a first resonance, the second branch defines a second resonance, and the third branch defines a third resonance, all of which are superposed to define a bandwidth of the radiating element that is substantially equivalent to the predefined operating frequency band of the RF front end.
