Patent attributes
A monopole antenna apparatus with dual purposes of being a multi-band mobile phone and a global positioning system. The antenna is formed on a substrate, and the substrate comprises a flat surface, a cambered surface, a first radiating metal line, including one high-frequency resonant path and one low-frequency resonant path, a second radiating metal line, a first feeding point, and a second feeding point. The high-frequency resonant path and the low-frequency resonant path for receiving and transmitting the signals of the multi-band mobile phone system are formed on the flat surface and the cambered surface separately, and both are connected to the first feeding point. The second radiating metal line for receiving the signals of the global positioning system is formed on the cambered surface and is connected to the second feeding point.
