Abstract
Millimeter-wave wireless systems offer high data rate, low latency, improved spectral efficiency and channel capacity, mainly when used in multiple-input multiple-output (MIMO) technology. Therefore, millimeter-wave antennas are explored to meet the user requirements of high throughput, with a very close distance between antenna elements to enable miniaturization.
However, antenna miniaturization at millimeter-wave bands has been a growing concernamong antenna engineers because of the inevitable, undesired mutual coupling between the antenna elements. This reduces the overall efficiency and gain of the MIMO antennas.
In this talk, I will demonstrate the efforts done in my research group to address the millimeter-wave antenna design challenges. Recently, we proposed a self-isolated 5G millimeter-wave MIMO tightly spaced antenna array with measured isolation (>50 dB) over the 28-38 GHz frequency band. Several rigorously optimized slots of different shapes, positions, and dimensions are etched on the radiating patch to enhance the inter-element isolation within 28-37.5 GHz impedance bandwidth. Additionally, the printed ridge gap waveguide (PRGW) technology will be demonstrated as a low loss millimeter-wave antenna array's feeding mechanism.
