Synthesis of Flat-topped Beams in Wireless Power Transmission

  • 摘要: 平頂波束在無線能量傳輸中能夠保證接收端功率密度的均勻性,對(duì)提高接收效率以及簡(jiǎn)化整流電路的設(shè)計(jì)具有重要意義。該文首先基于Orchard綜合,控制Schelkunoff單位圓零點(diǎn)位置,得到了實(shí)現(xiàn)平頂波束的條件;然后通過引入Sinc函數(shù),給出了平頂波束的解與平頂寬度的對(duì)應(yīng)關(guān)系;最后利用微擾法編程計(jì)算,討論了平頂寬度與矩形系數(shù)、波紋系數(shù)、副瓣電平之間的數(shù)值關(guān)系。以一款10元陣為例,實(shí)現(xiàn)了副瓣低于且寬度很窄的平頂波束,驗(yàn)證了該文方法和結(jié)論的有效性。
