A dual-band optics design for disjoint spectral bands and for a cooled FPA sensor, sensitive to both bands, is presented. The use of special optical splitting mechanisms enables matching the optical paths of both bands to the same sensor. Reasonable optical performance and good registration were achieved for dual bands such as 8 to 12 μm together with ...

A dual band gap slotted patch electromagnetic band gap for dual band microstrip antenna
2008 IEEE International RF and Microwave Conference, 2008This paper described the design of the dual band gap slotted patch EBG structure. By introducing double L slot into each EBG patch, a smaller rectangular patch has been introduced in each EBG patch resulting to the achievement of the second stop band frequency. The comparison between mushroom EBG structures has been investigated.

Dual‐band/dual‐polarized microstrip patch antenna for dual‐band heterodyne retrodirective array
Microwave and Optical Technology Letters, 2012AbstractThis article presents a dual‐band/dual‐polarized microstrip patch antenna.For a dual‐band retrodirective array system, the dual‐band/dual‐polarized microstrip patch antenna operating at 11 and 12.2 GHz is designed and tested. The antenna consists of one rectangular microstrip patch and a square ring outside of the patch.

Design of Dual-Polarized Dual-Band Unit-Cell for Wideband FSS in Ku Band
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019This paper proposes a dual-polarized frequency selective surface (FSS), designed in Ku and K bands which can be used as passband multilayer spatial filter. This design consists of double-sided unit-cells comprising a cross-dipole and a stubbed square loop, arranged in a square lattice.

Dual band/wide band waveguide polarizer
2000 Asia-Pacific Microwave Conference. Proceedings (Cat. No.00TH8522), 2002The design of a wide band iris or corrugated polarizer covering two separate bands is discussed here. By making use of thick irises with close spacing, a compact polarizer with fewer irises and a shorter electrical length can be designed with high performance characteristics. Such a polarizer was built and tested.
