| Abstract: | A UHF-band high-gain wideband Yagi antenna array is introduced.The working bandwidths of over 10% of the antenna elements are realized in combination with the special programming of the Yagi antenna through the integrated optimization of the HF software with the Yagi antenna vibrators as the array elements and the U-shape tube balanced and unbalanced converters as the matching.Several technical difficulties are solved through the engineering design and test,and the predetermined requirements of the overall ... |
