ANTENNA ELEMENT Russian patent published in 2008 - IPC H01Q13/24 

FIELD: microwave engineering; transceiving antennas for local industrial networks.

SUBSTANCE: proposed antenna element has dielectric resonator in the form of dielectric disk, coaxial line section with central conductor connected to cylindrical conductor, and space-enclosing conductive wall. Dielectric disk extends length l beyond space. Conductor section whose longitudinal axis is aligned with dielectric disk axis excites electromagnetic waves in the latter, their field structure corresponding to that of dielectric resonator E-waves. Dielectric disk axis is perpendicular to conductive wall surface. Effective excitation of E-waves in dielectric disk is ensured when its thickness is chosen from equation , where h is dielectric disk thickness; D is its diameter. Dielectric disk extends l = h - δ beyond space, where h is dielectric disk thickness; δ is conductive wall thickness amounting to 0.1-0.3 of dielectric disk thickness l.

EFFECT: enlarged passband and enhanced gain.
