Finally , in view of the absorbed po ~ ver of the terminated load and the realizablity of couplers , a proper eclectic distribution of coupling degree of couplers is computed synthetically . 2 . a small , light , compact , ~ vide band and high performance h - t coupler with lognitudinal dualslot is presented 根據(jù)天線方向圖要求,確定陣面的口徑分布,在此基礎上,結(jié)合慢波線終端負載的吸收系數(shù),以及耦合器耦合量的可實現(xiàn)性,綜合折中考慮,計算選擇出合適的耦合器耦合度分布。
