[作者:Jiang, H; Lacroix, B; Choi, K; Wang, YQ; Hunt, AT; Papapolymerou, J,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:3068-3075 , 文章类型: Article,,卷期:2011年59-12]
- This paper presents the realization of two secondorder quasi-elliptic ferroelectric tunable bandpass filters for millimeter-wave applications in Ka- and U-band, respectively. These filters include a coplanar-waveguide to...
- Single-Antenna Doppler Radars Using Self and Mutual Injection Locking for Vital Sign Detection With Random Body Movement Cancellation
[作者:Wang, FK; Horng, TS; Peng, KC; Jau, JK; Li, JY; Chen, CC,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:3577-3587 , 文章类型: Article,,卷期:2011年59-12]
- This work presents a single-antenna self-injection-locked (SIL) radar to reduce the hardware complexity of continuous-wave (CW) Doppler systems. The theory provides a basis for determining the signal-to-noise spectral de...
- Tunable Inter-Resonator Coupling Structure With Positive and Negative Values and Its Application to the Field-Programmable Filter Array (FPFA)
[作者:Lee, J; Naglich, EJ; Sigmarsson, HH; Peroulis, D; Chappell, WJ,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:3389-3400 , 文章类型: Article,,卷期:2011年59-12]
- In this paper, we show a tunable inter-resonator coupling structure capable of varying the coupling coefficient between resonators from positive to negative values, including values that approach zero. The presented inte...
