I-coaxial resonator, ebizwa nangokuthi i-dielectric resonator, uhlobo olusha lwe-resonator eyenziwe ngokulahleka okuphansi, izinto ezihlala njalo ze-dielectric ezifana ne-barium titanate ne-titanium dioxide. Ivamise ukuba ngunxande, isilinda, noma isiyingi.Isetshenziswa ku-Band Pass Filter (BPF), Voltage Controlled Oscillator (VCO). Ubuchwepheshe bokugxiviza okomile bekhwalithi ephezulu kanye nobuchwepheshe bokucubungula okuphezulu busetshenziselwa ukufeza imvamisa ezinzile.
