发明名称 Antenna structure for mobile telecommunication systems e.g. GSM system
摘要 The antenna structure has a planar antenna element (100) and a ground plane so that the antenna element is short-circuited to the ground plane at least at one place. The antenna element has two separate resonance frequencies. The antenna element also has two connection points (110,120). The connecting points are for connecting the feed lines of the antenna structure. The resonant frequencies are formed by two lips (10,102)
