Dual polarized dual‐band MIMO antenna

Microwave and Optical Technology Letters, 2016
ABSTRACTFor 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, 2008
This 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, 2013
A 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), 2018
In 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.
