| Abstract: |
| Objective To design a small Г-type antenna with filtering and miniaturization characteristics for modern wireless communication system. Methods This antenna with filtering characteristic was designed of two hairpin resonators, a coupling line and a Г-type antenna through a method which is similar to filter synthesis. The coupling line not only played a role of connecting antenna with hairpin resonator, but also a admittance converter. So this Г-type antenna was a resonator of the filter as well as the radiation. Results This design not only reduced the size of the integrated design of the filter and the antenna, but also made the signal transmission loss smaller. Conclusion The impedance bandwidth of the filter antenna is 6.5% (2.38-2.54 GHz) with the reflection coefficient <10 dB. Outside the pass band, the gain decline rapidly. The gain at 2.15 GHz and 2.75 GHz gain is 15 dBi and 25 dBi respectively. |
