双频天线
摘要：
本发明涉及一种双频天线，包含一第一辐射单元、一第二辐射单元、一微带线单元以及一接地单元。第一辐射单元具有一蜿蜒部。第二辐射单元与第一辐射单元连接，且第二辐射单元具有一缺口。微带线单元与第一辐射单元之间具有一锐角，且微带线单元包含一第一端、一第二端及一馈入点，其中，第一端分别与第一辐射单元及第二辐射单元连接，第一辐射单元与该微带线单元之间形成一共振腔。接地单元与微带线单元的第二端连接，且接地单元具有一接地点。
摘要（英）：

The invention relates to a dual-frequency antenna, which comprises a first radiation unit, a second radiation unit, a microstrip line unit and an earthing unit. The first radiation unit is provided with a winding part. The second radiation unit is connected with the first radiation unit, and is provided with a gap. An acute angle is formed between the microstrip line unit and the first radiation unit, and the microstrip line unit comprises a first end, a second end and a feed-in point, wherein the first radiation unit and the second radiation unit are respectively connected with the first end, and a resonant cavity is formed between the first radiation unit and the microstrip line unit. The earthing unit is connected with the second end of the microstrip line unit, and the earthing unit is provided with an earthing point.
