Dual-band dual polarization microstrip antenna
IEEE Antennas and Propagation Society International Symposium. Digest. Held in conjunction with: USNC/CNC/URSI North American Radio Sci. Meeting (Cat. No.03CH37450), 2004This paper describes the development of a multilayer dual-band dual-polarized antenna operating at L and C bands with a common aperture. Unlike earlier approaches, slot coupled patches are employed at both bands to reach cross-polarization suppression better than 30 dB.

Dual-band dual-polarization antenna array
2014 International Symposium on Antennas and Propagation Conference Proceedings, 2014This paper is proposed a dual-band dual-polarization antenna array. This antenna is combined by one 2 × 2 dual-polarization patch antenna array and two 1 × 4 dipole antenna arrays operated in ISM 2.4-Ghz/5.2-GHz band. For the purpose to achieve dual band operation, the microstrip line diplexer is applied to combine two antenna operated in 2.4-GHz and 5.

Dual polarized dual‐band MIMO antenna
Microwave and Optical Technology Letters, 2016ABSTRACTFor multiple‐input‐multiple‐output (MIMO) system a dual‐band dual‐polarized antenna is presented. The antenna which is presented in this thesis produces a linearly polarized and circularly polarized radiation fields. The measured return losses of −18.89 and −21.86 dB are achieved at 2.43 GHz and 3.22 GHz, respectively.

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 Crossed-Dipole Reflectarray With Dual-Band Frequency Selective Surface
IEEE Antennas and Wireless Propagation Letters, 2013A novel dual-band reflectarray comprising crossed-dipole elements and dual-band frequency selective surface (FSS) printed on both sides of a dielectric substrate is presented. The dual-band FSS function is used as a reflective ground plane. Compared to the dual-band reflectarray backed by a solid ground, the dual-band FSS-backed reflectarray could ...

A Compact Dual-Band and Dual-Polarized Electromagnetic Band-Gap Structure
2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE), 2018In this paper, we present a compact dual-band and dual-polarized Electromagnetic Band-Gap (EBG) structure. The unit cell is composed of an inner folded rotated Jerusalem cross cell and four outer T-shaped cells. All of cells are connected with ground by via.
