Double H-shaped metamaterial resonator for low phase noise voltage controlled oscillator

초록

In this article, we propose a voltage controlled oscillator (VCO) using a double H-shaped metamaterial resonator (DHMR) based on a high Q value.The proposed DHMR exhibits a metamaterial characteristic which has a zero phase coefficient at the vicinity of resonance frequency. The proposed DHMR is designed to be a high Q by a strong coupling of the E-field at the resonance frequency. These characteristics made phase noise performance in the synthesizer using the proposed VCO excellent. The proposed VCO with DHMR is designed to apply to an X-Band frequency synthesizer of radar systems. The output power, the phase noise and the tuning range are 7.33 dBm, -121.3 dBc/Hz at 100 kHz offset carrier frequency and over 120 MHz, respectively. (c) 2012 Wiley Periodicals, Inc.
