Some aspects of stability and numerical dissipation of the finite-difference time-domain (FDTD) technique including passive and active lumped elementsIEEE Transactions on Microwave Theory and Techniques - Tập 50 Số 9 - Trang 2159-2165 - 2002
W. Thiel, L.P.B. Katehi
This paper presents a stability analysis of the extended finite-difference time-domain method including passive and active devices. An explicit, implicit, and semi-implicit incorporation of lumped elements is investigated and the eigenvalues of the resulting discrete system are discussed. With the underlying assumption that the domain is homogeneously loaded with lumped elements, stability criteri...... hiện toàn bộ

A novel amplifying antenna array using patch-antenna couplers-design and measurementIEEE Transactions on Microwave Theory and Techniques - Tập 50 Số 8 - Trang 1919-1926 - 2002
Chih-Hung Tsai, Y.A. Yang, Shyh-Jong Chung, Kai Chang
This paper proposes a novel amplifying antenna array using the patch-antenna coupler formed by placing one or two open-ended microstrip lines (coupled lines) near and along the nonradiating edge(s) of a patch antenna. An X-band five-element array with broadside 25-dB Chebyshev radiation is demonstrated. When the input signal is fed to the center element, with most of the power radiating from the a...... hiện toàn bộ

Small-signal and temperature noise model for MOSFETsIEEE Transactions on Microwave Theory and Techniques - Tập 50 Số 8 - Trang 1927-1934 - 2002
A. Pascht, M. Grozing, D. Wiegner, M. Berroth
The present CMOS technology provides n-channel MOSFETs with a transit frequency beyond 30 GHz, which are attractive for RF integrated circuits, e.g., low-noise amplifiers. This paper presents an improved deembedding procedure for extraction of parasitic elements of MOSFETs. The extraction determines the intrinsic elements of the small-signal equivalent circuit. As a result, a new method to determi...... hiện toàn bộ

5.8-GHz circularly polarized rectifying antenna for wireless microwave power transmissionIEEE Transactions on Microwave Theory and Techniques - Tập 50 Số 8 - Trang 1870-1876 - 2002
B. Strassner, Kai Chang
This paper reports a new circularly polarized (CP) high-gain high-efficiency rectifying antenna (rectenna). The CP rectenna can be rotated and still maintain a constant dc output voltage. The high-gain antenna has an advantage of reducing the total number of rectenna elements to cover a fixed area. The rectenna is etched on Rogers Duroid 5870 substrate with /spl epsi//sub r/=2.33 and 10 mil thickn...... hiện toàn bộ
