A Metamaterial-Loaded Pattern-Reconfigurable Antenna with Dielectric Decoupler for MIMO Applications
This presentation delves into an advanced pattern-reconfigurable antenna tailored for 4-port MIMO applications. The antenna incorporates a distinctive dielectric decoupler with a boundary designed to create electric field valleys, optimally placed to augment isolation between ports. Additionally, the presence of cross-shaped cavities in the dielectric decoupler further improves the antenna's isolation properties. The integration of a loaded metamaterial layer results in a more compact antenna design. Significantly, this MIMO antenna has the ability to modify its radiation patterns by activating various ports.

A Metamaterial-Loaded Pattern-Reconfigurable Antenna with Dielectric Decoupler for MIMO Applications
In modern wireless communications, integration with wireless local area network (WLAN) systems, radio frequency identification (RFID) systems, and global positioning systems has led to diverse and complex requirements for antenna frequency bands, radiation patterns, and polarization modes. To address these challenges and enhance the integration of communication equipment components, researchers are increasingly exploring reconfigurable antennas. While traditional methods for achieving reconfigurability, such as using PIN diodes and MEMS, introduce nonlinear losses, a 4-port MIMO antenna capable of achieving four different radiation patterns by exciting different ports is presented in this discussion. With antennas featuring multiple ports, it's critical to consider the isolation between each port. Although various decoupling methods, including defected ground structures (DGS), parasitic elements, and metamaterials, have been proposed, they are often challenging to fabricate. In this presentation, the use of a dielectric decoupler to enhance port isolation is examined. The dielectric-air boundary (DAB) properties successfully create electric field valleys in the dielectric, effectively decoupling the ports. Additionally, the addition of a circular metamaterial layer on top of the antenna serves to reduce its size effectively.

A Metamaterial-Loaded Pattern-Reconfigurable Antenna with Dielectric Decoupler for MIMO Applications
This presentation introduces a 4-port MIMO antenna with a dielectric decoupler to create reconfigurable radiation patterns. By exciting different ports, four radiation patterns can be achieved. By optimizing the dielectric decoupler's dimensions, electric field valleys can be generated at specific locations, allowing for the placement of monopole antennas at these valleys. This approach results in excellent isolation characteristics for the proposed MIMO antenna. Additionally, a top-loaded metamaterial plane is employed to reduce the dielectric's size, enabling the design of a more compact antenna in the UWB band.
