| Abstract: | To probe into the approach of array antenna with high power and high gain,a square helical array antenna fed from a radial line was proposed and designed,and its fundamental principle was presented.The radiation element,the coupling probe and the feeding system were designed in details,as a result,an X-band 4-element array model was obtained.The numerical simulation result of the array model shows that in the range of 8.5 to 10.3 GHz,the antenna reflectance is below 0.1,the antenna gain is over 12 dB,and the antenna axial ratio is below 1.9. |
