超增益天線 的英文怎麼說
中文拼音 [chāozēngyìtiānxiàn]
超增益天線
英文
super gain antenna-
With the developing of new switches such as photoconductive switch and sos ( solid opening switch ), both high power and high gain can be got by the uwb antenna array
隨著各種新型開關如大功率的光導開關的研究成功，超寬帶天線陣列將成為實現高功率、高增益的有效途徑。Many technologies of electrically small antennas and wide band antennas are discussed in theory, simulation and experiment. and some novel electrically small or wide band antennas are proposed. the loaded monopole is analyzed in depth integrating the genetic algorithm ( ga ) with the method of moments ( mom ) in order to increase the gain and decrease the vswr of antennas used at hf / vhf band
在本論文的研究過程中，通過合理利用各種現有的天線寬帶化和小型化的理論成果、有效的綜合各種技術措施，運用矩量法和遺傳優化演算法等數值方法，深入研究了加載單極子天線問題，旨在全面提高高頻/甚高頻頻段內的天線增益和降低電壓駐波比，以獲得較高增益的、基本滿足駐波要求的小型超寬帶天線。At last, two circular monopole ultra - wideband antennas with different radius are made. by experiments, the return loss, radiation pattern and gain of the
最後，本課題實際製作了不同尺寸的圓盤單極超寬帶天線，分別測量了天線的反射損耗，方向圖和增益，並與模擬結果加以比較。
