Dual-band X/Ku Reflectarray Antenna Using a Novel FSS-Backed Unit-Cell with Quasi-Spiral Phase Delay Line

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
A novel FSS-Backed reflectarray unit cell is introduced to design a dual-band X/Ku Reflectarray Antenna (RA). A Ku-band RA based on this FSS-Backed cell element is designed and located on the top of a conventional X-band RA.

A photometric survey for Lyalpha-HeII dual emitters: Searching for Population III stars in high-redshift galaxies

, 2008
We present a new photometric search for high-z galaxies hosting Population III (PopIII) stars based on deep intermediate-band imaging observations obtained in the Subaru Deep Field (SDF), by using Suprime-Cam on the Subaru Telescope. By combining our new

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

Reflex feed system for dual frequency antenna with frequency cutoff means [PDF]

, 1978
A reflex feed system is described for a dual frequency antenna such as one which transmits and receives both S and X band signals. The dichroic plate, normally employed for directing X band radiation away from the X band horn, is replaced by a flange ...

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
