The proposed oscillator utilizes a novel complementary coupled resonator based on substrate integrated waveguide (SIW) that has a broad tuning range of 8.84% relative bandwidth, and thereby achieves a continuous tuning oscillation range from 4.85 GHz to 5.1 GHz, or a 5.15% relative bandwidth of the proposed tunable oscillator with a low phase noise of -115.2 dBc/Hz and a DC-RF conversion efficiency of 19%.coupled slot resonator | Substrate integrated waveguide (SIW) | tunable resonator | voltage-controlled oscillator (VCO)[SDGs]SDG7A C-band tunable oscillator based on complementary coupled resonator using substrate integrated waveguide cavityconference paper10.1109/EuMC.2014.69865342-s2.0-84929232161https://api.elsevier.com/content/abstract/scopus_id/84929232161
