Dual band planar folded monopole
2010 International Workshop on Antenna Technology (iWAT), 2010In this paper an improved design of a dual band planar folded monopole is proposed. A folded monopole antenna is constructed by truncating the folded dipole antenna by half and attaching the ground plane. The planar folded monopole has been analyzed theoretically and experimentally. The design was extended to a dual band operation.

A dual-band BPF for concurrent dual-band wireless transceiver
Proceedings of the 5th Electronics Packaging Technology Conference (EPTC 2003), 2004The development of concurrent dual-band wireless transceiver has enhanced the miniaturization of all blocks used in the wireless transceiver. That is achieved by casting the two single-band blocks into a dual-band block. In this paper, a dual-band BPF for the concurrent dual-band wireless transceiver is developed. A stepped impedance resonator (SIR) is

Third‐order dual‐band filter with dual‐band admittance inverter
Microwave and Optical Technology Letters, 2010AbstractIn this article, stepped impedance resonator with dual‐band admittance inverter is proposed to design the dual‐band microstrip filter to operate at (2.4, 5.2) GHz and at (0.9, 2.3) GHz, respectively. The proposed dual‐band microstrip filter consists of stepped‐impedance resonators (SIRs) in shunt cascaded by dual‐band inverter.

Optical Engineering, 2013
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 ...

Dual-Band Transmitarrays With Dual-Linear Polarization at Ka-Band
IEEE Transactions on Antennas and Propagation, 2017Dual-band transmitarray antennas are demonstrated at Ka-band with the capability of forming independent linearly polarized beams with a given polarization in each frequency band, while sharing the same radiating aperture. The proposed three-layer unit-cell is based on identical narrow microstrip patches printed on both receiving and transmitting layers

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.

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.

Dual-Band dual-polarized patch antennas
International Journal of Microwave and Millimeter-Wave Computer-Aided Engineering, 1995AbstractTwo new configurations of patch antennas are introduced, which provide dual‐band and dual‐polarization operations. The two patches have a square and cross shape, and are printed on a single layer; the dual‐frequency and the dual‐polarization behavior is obtained by means of four narrow slots close to the edges.

Dual-band dual-polarization microstrip antenna
IEEE Antennas and Propagation Society International Symposium (IEEE Cat. No.02CH37313), 2003The analysis of a single patch microstrip antenna based on the impedance model, emphasizing mainly the design considerations for dual-band and dual-polarization, is presented here. A length compensation technique is proposed to achieve the exact dual mode resonance with the desired accuracy.
