A high-gain Y-shaped patch array with an 8-port MIMO configuration for pattern diversity in mm-wave applications.

Area of Science:

• Electrical Engineering
• Electromagnetics
• Wireless Communication

Background:

• The growing need for high-speed data transmission necessitates advanced antenna solutions for millimeter-wave (mm-Wave) 5G applications.
• Existing antenna designs often face limitations in achieving both high gain and comprehensive pattern diversity required for next-generation wireless networks.

Purpose of the Study:

• To design and evaluate a novel 8-port Multi-Input-Multi-Output (MIMO) antenna system for 28 GHz mm-Wave 5G applications.
• To achieve 360° pattern diversity and enhanced gain using a unique array configuration.

Main Methods:

• The proposed antenna utilizes a fully covered ground plane on a Rogers RT-droid 5880 substrate.
• An unconventional three-element array configuration was developed to boost the gain of the unit element.
• The array was extended to an eight-port MIMO configuration to enhance system performance.

Main Results:

• The unit antenna element achieved a gain of 7.37 dBi, which was improved to 12 dBi in the three-element array.
• The antenna array demonstrated an operational bandwidth of 800 MHz (27.6-28.4 GHz).
• The eight-port MIMO configuration enhanced data throughput, spectral efficiency, and spatial diversity.

Conclusions:

• The developed mm-Wave MIMO antenna offers a viable solution for 5G communication, radar systems, and point-to-point links.
• The design successfully balances gain enhancement with a manageable trade-off in bandwidth.
• The antenna's 360° beam steering capability significantly improves the efficiency of modern wireless systems.
