  1. A patch antenna with etched holes on the ground plane is also studied. the performance of the antenna at the resonant frequency is analyzed by using the fdtd method together with the pml boundary treatment. the results show that the surface waves are suppressed greatly, the bandwidth is improved and a 1 odb reduction on the sidelobe level is achieved at the 110 and 260 directions in the e plane

    全面地研究了地面腐蝕周期圓孔結構的電磁晶體貼片天線在基波頻率處的性能，用fdtd方法並結合pml邊界處理技術對該天線所取得的研究結果顯示，本文設計的地面腐蝕型電磁晶體結構抑制了貼片天線中的表面波，增加了天線的帶寬，並有效地削弱了旁瓣，使天線的e面方向圖上110和260方向的兩個旁瓣被削弱了10db 。
  2. A patch antenna with air holes in the substrate has been designed. the finite - difference time - domain ( fdtd ) method together with the perfectly matched layer ( pml ) boundary treatment has been used to study the performance of the antenna. it is shown that the surface waves are significiently suppressed, the frequency bandwidth is improved, the sidelobe levels are reduced and consequently the gain in the forward direction is improved by 14 db ( about 4 db higher than the value reported previously )

    設計了一種基底鉆周期圓孔結構的電磁（光子）晶體貼片天線，用fdtd方法並結合pml吸收邊界條件對該天線進行了研究，結果表明本文所設計的基底鉆孔型電磁晶體貼片天線取得了多方面的性能改善，與普通天線相比，基底中的表面波受到很大抑制，天線的帶寬增加，遠場方向圖上天線的旁瓣和背瓣被明顯削弱，向前輻射的增益由原來的12db增加到26db ，增加了14db ，比文獻上報道的gonzalo等人的研究結果提高了4db 。
  3. Usually the frequency bandwidth of microstrip patch antenna is relatively narrow. however, it can be effectively broadened with the employment of the micro - electro - mechanism systems technique to fabricate microstrip antenna with multilayer dielectric substrates and patch

    通常微帶貼片天線的頻帶較窄，而利用微電子機械繫統（ mems ）技術製作具有多層介質和貼片結構的微帶天線，可以有效地擴展天線的帶寬。
  4. Generally speaking, the increase of the slot length and width can make the resonance frequency low, which is not the longer the better, however

    一般來說，縫隙長、寬的增加可使諧振頻率點降低，而較大的縫寬也降低了貼片的有效輻射面積，使增益降低，所以需要折衷協調。
  5. Sawblade for ripping and cross cutting of softwoods and hardwoods up to 50mm and single or multiple chipboard panels up to 60mm with good finish. use on table saws

    用於切割各種塑料雙貼面刨花板的預劃槽，以消除貼面崩裂現象。鋸片寬度從2 . 8毫米可調到3 . 6毫米。
  6. Broadband microstrip patch antenna using a superstrate layer

    添加覆蓋層的寬帶微帶貼片天線
  7. The way of widening the band is realized by employing the inverted parasitic patch and the thick and low dielectric constant substance. with this treatment, the relative band of the antenna can be widened up to 20 %. and by adopting the way of two h - slots arranged in a “ t ” configuration, the isolation is improved

    微帶天線的頻帶展寬通過採用倒懸寄生貼片和較厚的低介電常數的介質來實現，經過這樣處理后的天線帶寬可以達到20 %以上;而隔離度的改善則是採用了兩個h形縫隙排列成「 t 」型結構。
  8. Study of multi - band property of rectangular microstrip patch antenna having different numbers of wide slots

    具有不同寬槽數的矩形微帶貼片天線多帶特性研究
  9. Study on broad - band microstrip patch antenna

    寬頻帶微帶貼片天線研究
  10. Stacked wide band microstrip antenna

    雙層寬帶微帶貼片天線
  11. The samples of the trademarks must be clear, easy to paste, printed on durable paper with a smooth finish or, instead of being printed, photographed ; they shall not be larger than ten centimeters or less than five centimeters in length and width

    商標圖樣必須清晰、便於粘貼，用光潔耐用的紙張印製或者用照片代替，長和寬應當不大於十厘米，不小於五厘米。
  12. The use of aperture coupled feeding widens the working band and increases the isolation. simultaneously, the application of round patch can upgrade the gain and radiation efficiency of the antenna

    採用口徑耦合饋電能夠展寬帶寬，提高隔離度，而採用圓形作為貼片形狀可以提高天線的增益和輻射效率。
