Abstract
The utility model discloses a four frequency band printed antenna used for receiving and transmitting electromagnetic wave signals in four different frequency bands. The four frequency band printed antenna includes a substrate and a conducting layer formed on a front face of the substrate. The conducting layer includes a feeding terminal, a grounding terminal and a connection part formed by extending along the feeding terminal forward. The connection part extends to the left and forms a first high frequency part controlling a fourth frequency band. The connection part extends to the left front and forms a low frequency part controlling a first and a second frequency band. The connection part extends to the right front and forms a second high frequency part controlling the third frequency band. The low frequency part distributes in the left front of the first high frequency part in a buckling manner and forms a trapezoidal first gap with the first high frequency part. In the utility model, the trapezoidal first gap is arranged between the low frequency part and the high frequency part. The trapezoidal first gap effectively widens a low frequency band in the four frequency band printed antenna, thereby enabling the four frequency band printed antenna to meet communication standard requirements in various systems.
