【天線】一個 Research topic 的理解
|
|
此課題關(guān)于天線在局域網(wǎng)絡(luò)中的應(yīng)用,大家都來談一下自己的理解,特別是紅字部分。具體的問題如下,請大家指教 1. 為何“LMDS覆蓋角度為600°~900°的區(qū)域,因此需4~6臺發(fā)射機覆蓋整個區(qū)域” With the emergence of local multipoint distribution services (LMDS) that operate millimeter-wave signals in the 28GHz spectrum to provide services such as television, video on demand, internet access, interactive games as well as a host of other services to homes and offices, we aim at designing a shaped beam microstrip patch antenna array operating at 28GHz. Our design is suitable for applications such as hub to hub and hub to subscriber connections. Eight element and sixteen element arrays were designed and fabricated. The experimental data agree well with the simulated results. [ Last edited by Yaniel on 2010-11-22 at 20:44 ] |
