| Abstract: | A triangle-grid radial-line helical rectangular array antenna was proposed. Based on the backgrounds and the principle of the array antenna, the 8-element triangle-grid radial-line helical rectangular array antenna was studied by the numerical simulation at the central frequency of 4.0 GHz and experiments. Experimental results indicate that: at the central frequency of 4.0 GHz, the power gain is 15.3 dB, the axial ratio is 1.58 at the normal direction, the voltage standing wave ratio(VSWR) is 1.3 and the aperture efficiency is 86%. In the range of 3.8 GHz to 4.2 GHz, the power gain is above 14.9 dB, the axial ratio is below 1.7 and the VSWR is below 1.6． |
