Abstract
The utility model discloses a three-frequency hidden antenna engaged inside electronic consumptive products such as the cell phones or the like, which comprises a body of the antenna. First trench and second trench are formed on the body of the antenna, thereby forming the first branch and the second branch. Further the courses of the two trenches are of approximately the same length and a feed point is arranged on the first branch and an earth point is arranged on the second branch. Thereby the antenna body vibrates harmonically with the low frequency electromagnetic wave to receive and transmit the low frequency electromagnetic wave signals and the first trench vibrates harmonically with the high frequency electromagnetic wave to receive and transmit the high frequency electromagnetic wave signals. When the first trench is receiving and transmitting the electromagnetic wave signals, the second trench vibrates together with the first trench, thereby widening range of high frequency band of the first trench which is capable of receiving and transmitting the electromagnetic wave signals and increasing the gain values. Thereby, the hidden antenna is capable of receiving and transmitting three-frequency electromagnetic signals.
