Title:
新しい誘電体共振器形アンテナの共振モード
Document Type and Number:
Japanese Patent JP2005521315
Kind Code:
A
Abstract:
There is disclosed a dielectric resonator antenna adapted to resonate in an EH resonance mode. The desired resonance mode is achieved by careful positioning of a dielectric resonator (20) on a grounded substrate (23), the resonator (20) being fed by way of a direct microstrip feed line (25). Because the EH resonance mode has nulls in a direction of longitudinal extension of the dielectric resonator (20), a plurality of antennas can be placed end-to-end so as to form an array with reduced coupling between adjacent antennas and with vertical polarisation, which is desirable for mobile communications applications.
