Compact Dual-band Filtering Power Divider with Low Loss and High Isolation Based on Open-Circuited Stepped-impedance Resonators [PDF]

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
In this paper, a novel, compact, and high-performance dual-band filtering power divider is presented. The proposed circuit is constructed from a dual-band power divider and open-circuited stepped-impedance resonators.

Dual Band Microstrip Antenna

Tecnología y Ciencia
The amount of data in today’s communication systems is increasing considerably, which in turn increases the bandwidth needed to deploy a given service. This requires antennas that are capable of operating simultaneously in more than one band.

Miniature Multi-Band Absorptive Bandstop Filter Designs Using Bridged-T Coils

IEEE Access, 2018
In this paper, miniature absorptive bandstop filters (ABSFs) with one to three stopbands are demonstrated. First, the proposed single-band ABSF is realized by the introduction of one lossy resonator to a conventional stub bandstop filter, while the ...

Dual-band single-pixel telescope [PDF]

Optics Express, 2020
Single-pixel imaging systems can obtain images from a wide range of wavelengths at low-cost compared to those using conventional multi-pixel, focal-plane array sensors, especially at wavelengths outside the visible spectrum. The ability to sense short-wave infrared radiation with single-pixel techniques extends imaging capability to adverse weather ...
