Summary: | The utility model relates to a three frequency antenna, which belongs to resonant slot antennae. The aim of the utility model is to solve the problems that the manufacture of an existing multifrequency antenna is complicated, and the signal of each frequency band has crosstalk. The three frequency antenna comprises a grounding part and a first to a fifth radiation parts which are arranged on one side of the grounding part, wherein, the first and the fourth radiation parts are respectively positioned on both sides of the second radiation part, and are vertical to the second radiation part, the third and the fifth radiation parts are orderly positioned on one vertical side of the second radiation part, and share one surface with the second radiation part, a first frequency band electric field is formed between the first and the second radiation parts, a second frequency band electric field is formed between the third and the fifth radiation parts, and a third frequency band electric field is formed between the third and the fourth radiation parts. The utility model is suitable for a portable communication device. |
