Design and Fabricate the UWB Tapered Fed Printed Log-Periodic Dipole Antenna with Dual Notched Band Using Double Side SRR [PDF]

International Journal of Research and Technology in Electrical Industry
In this paper, proposed a notch filter using the parallel microstrip line with a pair of rectangular C-shaped split ring resonator (CSRR) that is placed on the top and bottom side of the substrate. The CSRR has a width (w), length (L), and the gap region

The impedance variation with feed position of a microstrip line-fed patch antenna [PDF]

Serbian Journal of Electrical Engineering, 2014
This paper presents a very precise analysis of the impedance variation with feed position of a microstrip line-fed patch antenna. The influence of the inset length and width has been investigated, taking into account finite size of the substrate,

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 ...

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.

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

Advanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...
