Title:
電磁バンドギャップ素子及びそれを用いたアンテナ並びにフィルタ
Document Type and Number:
Japanese Patent JP5550100
Kind Code:
B2
Abstract:
Conductor pieces 102 that are periodically arrayed, a conductor plane 103 that has openings 104 periodically arrayed so as to correspond to the conductor pieces 102, and a dielectric 108 that is arranged between the conductor pieces 102 and the conductor plane 103, are included. Island electrodes 105 and planar inductance elements 106 are arranged in the openings 104 of the conductor plane 103. The island electrodes 105 and the conductor pieces 102 are connected by conductor posts 107. The island electrodes 105 and the conductor plane 103 are connected through the planar inductance elements 106.
