| Abstract: | The paper presents a practical widebeam broadband satellite communication mobile terminal antenna. The antenna using gradient spiral arms and conical baffle structure to improve the performance of the conventional bifilar helix antenna. Combining the software HFSS and the theory analysis,the structure parameters of the antenna are designed and the simulation and experiment are performed. The simulation results fit the measured data very well. The satellite communication antenna, whose operating band is about 150MHz and the beam width is greater than 110°, is a left-handed circular polarization antenna at 1. 6GHz. The antenna structure is simple, secure , easy processing, suitable for all kinds of small mobile satellite communication terminals, as well as satellite communication at high latitudes. |
