每經訊，據啟(qi)信寶，新(xin)(xin)(xin)三(san)板創新(xin)(xin)(xin)層公司德卡(ka)科技(ji)（832423）新(xin)(xin)(xin)增(zeng)專利(li)信息，專利(li)權(quan)人為(wei)德卡(ka)科技(ji)，發明人是劉(liu)龍、賈立民。專利(li)授(shou)權(quan)日(ri)為(wei)2023年9月8日(ri)，專利(li)名(ming)稱為(wei)“NFC雙天線收發電路”，專利(li)類型為(wei)中國實用新(xin)(xin)(xin)型專利(li)，專利(li)申請號為(wei)CN202320904714.X。

該專(zhuan)利摘(zhai)要(yao)顯示：本實用(yong)新型公開了一(yi)種(zhong)NFC雙(shuang)天(tian)(tian)(tian)線(xian)(xian)收(shou)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)路(lu)，包括第(di)(di)(di)一(yi)天(tian)(tian)(tian)線(xian)(xian)電(dian)(dian)(dian)(dian)路(lu)，與(yu)(yu)收(shou)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)路(lu)連(lian)接(jie)；第(di)(di)(di)二(er)(er)天(tian)(tian)(tian)線(xian)(xian)電(dian)(dian)(dian)(dian)路(lu)，與(yu)(yu)收(shou)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)路(lu)的連(lian)接(jie)；收(shou)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)路(lu)，輸(shu)出(chu)端(duan)與(yu)(yu)識別電(dian)(dian)(dian)(dian)路(lu)的輸(shu)入端(duan)連(lian)接(jie)，用(yong)于將第(di)(di)(di)一(yi)射頻信(xin)(xin)號(hao)(hao)轉換成第(di)(di)(di)一(yi)差分(fen)信(xin)(xin)號(hao)(hao)或將第(di)(di)(di)二(er)(er)射頻信(xin)(xin)號(hao)(hao)轉換成第(di)(di)(di)二(er)(er)差分(fen)信(xin)(xin)號(hao)(hao)后輸(shu)出(chu)給識別電(dian)(dian)(dian)(dian)路(lu)；識別電(dian)(dian)(dian)(dian)路(lu)，輸(shu)出(chu)端(duan)與(yu)(yu)外部主機連(lian)接(jie)，用(yong)于接(jie)收(shou)第(di)(di)(di)一(yi)差分(fen)信(xin)(xin)號(hao)(hao)或第(di)(di)(di)二(er)(er)差分(fen)信(xin)(xin)號(hao)(hao)，并將第(di)(di)(di)一(yi)差分(fen)信(xin)(xin)號(hao)(hao)對應(ying)(ying)的第(di)(di)(di)一(yi)信(xin)(xin)息(xi)或第(di)(di)(di)二(er)(er)差分(fen)信(xin)(xin)號(hao)(hao)對應(ying)(ying)的第(di)(di)(di)二(er)(er)信(xin)(xin)息(xi)輸(shu)出(chu)給外部主機。本申請實現了識別電(dian)(dian)(dian)(dian)路(lu)與(yu)(yu)第(di)(di)(di)一(yi)天(tian)(tian)(tian)線(xian)(xian)電(dian)(dian)(dian)(dian)路(lu)和第(di)(di)(di)二(er)(er)天(tian)(tian)(tian)線(xian)(xian)電(dian)(dian)(dian)(dian)路(lu)的連(lian)接(jie)，可(ke)實現對不同的職能卡(ka)片的識別，也就滿足了NFC雙(shuang)天(tian)(tian)(tian)線(xian)(xian)收(shou)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)路(lu)的多場景應(ying)(ying)用(yong)需求，提高了NFC雙(shuang)天(tian)(tian)(tian)線(xian)(xian)收(shou)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)路(lu)的使用(yong)效率(lv)。
