技術摘要 / Our Technology: |
本發明係一種具有橫向矩形空腔之介電質共振器天線(DRA)及其設計方法,該介電質共振器天線包括一基板(substrate)、一接地層(ground plane)、一饋入導體(feed conductor)、以及一介電質共振器(dielectric resonator),該介電質共振器更包含一本體及一嵌入於該本體之空腔,該空腔具有增強電場,提升電磁場之輻射效率,增加傳輸頻寬之功能,並可產生新的共振模態,該介電質共振器天線具有寬波束之垂直極化輻射場型,本發明之介電質共振器天線可適用於WLAN 802.11a無線區域網路。
The present invention relates to a dielectric resonator antenna (DRA) with a transverse-rectangle well. The DRA comprising a substrate, a ground plane, a feed conductor, and a dielectric resonator. The resonator further includes a main body and a well penetrating the main body to enhance the electric field, to increase the radiation efficiency, to broaden the bandwidth, and to create new resonant mode. The DRA has the radiation pattern of broad beamwidth with vertical polarization. Accordingly, the invention can also be adjusted as WLAN 802.11a antenna.
