An analysis of microstrip with rectangular and trapezoidal conductor cross sections [PDF]

, 1990
The finite-difference time-domain (FDTD) technique is used to analyze boxed microstrip with both rectangular and trapezoidal cross sections. It is confirmed that the exact shape of the conductor has a marked effect on the effective permittivity of the ...

Terahertz Waveform‐Selective Antenna Using a Patch Structure Loaded with Nonlinear Circuits

Advanced Photonics Research, EarlyView.
A waveform‐selective antenna that integrates the functions of waveform selectivity, electromagnetic shielding, and EM wave radiation has been proposed. By integrating different nonlinear circuits and selecting appropriate component values, the antenna can achieve high reflection of either a pulse wave or a continuous wave, while allowing the other ...

Compact Broadband High-Directivity Microstrip Directional Coupler

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
The difference between phase velocities of the odd and even modes in inhomogeneous microstrip coupled lines makes the microstrip directional coupler a poor device regarding directivity. In this work, this issue is successfully compensated by the addition

Novel CMOS RFIC Layout Generation with Concurrent Device Placement and Fixed-Length Microstrip Routing

, 2017
With advancing process technologies and booming IoT markets, millimeter-wave CMOS RFICs have been widely developed in re- cent years. Since the performance of CMOS RFICs is very sensi- tive to the precision of the layout, precise placement of devices and

Microstrip ring resonator and dispersion measurement on microstrip lines

Electronics Letters, 1971
A theory is described which takes into account the curvature of the microstrip ring resonator. This curvature is shown to have a large influence on dispersion measurements on microstrip lines with small impedences.
