Electromagnetic compatibility aware design and testing of intermodulation distortion under multiple co-located sources illumination [PDF]

, 2012
Current electromagnetic immunity tests mainly rely on single-frequency sources. However, the evolution of electronic systems leads to miniaturisation and low-cost solutions, in which filters are omitted in front of active non-linear components, also for ...

Integrated Dual-Band Filtering/Duplexing Antennas

IEEE Access, 2018
In this paper, the state-of-the-art integrated filtering antennas with dual-band operation are first reviewed. Then, two designs of dual-band microstrip filtering antennas with a low-frequency ratio are presented.

GA Optimisation of Crossed Dipole FSS Array Geometry [PDF]

, 2001
Crossed dipoles are used as dual polarised elements in frequency selective surface arrays but the transmission response is angle of incidence dependent. A genetic algorithm has been used to minimise the drift of the reflection band, stabilising it for a ...

A Dual-Band Patch Antenna with Combined Self-Decoupling and Filtering Properties and Its Application in Dual/Squad-Band Two-Element MIMO Array

Sensors
This paper proposes a dual-band patch antenna with combined self-decoupling and filtering properties, designed to suppress mutual coupling between two antenna elements both within the same dual-band and across different dual-bands. Initially, a dual-band

High Efficiency Dual-Band Dual-Circularly Polarized Transmitarray Antenna

Micromachines
A dual-band dual-circularly polarized transmitarray antenna (TA) operating in the 28/39 GHz millimeter-wave band is proposed in this article. The TA unit consists of two parts: a broadband linearly polarized (LP) receiving part and a dual-band dual ...

Pattern Synthesis of Dual-band Shared Aperture Interleaved Linear Antenna Arrays [PDF]

, 2014
This paper presents an approach to improve the efficiency of an array aperture by interleaving two different arrays in the same aperture area. Two sub-arrays working at different frequencies are interleaved in the same linear aperture area. The available

Optimizing the G/T ratio of the DSS-13 34-meter beam-waveguide antenna [PDF]

, 1992
Calculations using Physical Optics computer software were done to optimize the gain-to-noise-temperature (G/T) ratio of Deep Space Station (DSS)-13, the Deep Space Network's (DSN's) 34-m beam-waveguide antenna, at X-band for operation with the ultra-low ...
