style="text-indent:25px">SIMcom無線通訊模塊用哪種天線好？天線是通信系統(tǒng)的重要組成部分，它性能的好壞直接影響通信系統(tǒng)的指標(biāo)，在挑選天線的時(shí)候一定要注重其性能，另外天線的增益是天線的重要指標(biāo)之一，它是方向系數(shù)與效率的乘積，是天線輻射或接收電波大小的表現(xiàn)。SIMcom無線通訊模塊用哪種天線？一般常用的無線模塊要求的天線阻抗為50歐姆，SIMcom無線模塊可使用通用的SIMcomMHz彈簧天線、彎頭/直頭棒狀天線、吸盤天線等，這些天線是為SIMcomMHz無線通信系統(tǒng)設(shè)計(jì)的**天線，天線駐波比性能好，結(jié)構(gòu)巧妙，安裝方便，性能穩(wěn)定，具有很好的防振動(dòng)和老化能力。用戶可根據(jù)自身的應(yīng)用環(huán)境來選購天線。無線通信模塊價(jià)格成本不但關(guān)系著客戶的利益，也和無線通信模塊生產(chǎn)廠商緊密相連。揚(yáng)州手機(jī)通信模塊</p><p
