Description of the thesis topic
With the 5G roll out and the perspective of dense network deployment of base stations to achieve the expect capacity, the antennas have to be more efficient with low profile and low cost.
An attractive and simple way to design low cost antennas is by reducing the number of antenna elements in the array. This is possible when the distance between the elements are greater than half wavelength.
However, the problem of these antenna array resides in the degradation of their performances when scanning away from broadside and are subject to the appearance of grating lobes. They are also pointed out as major interference generators to other existing communication systems especially to satellite services.
The purpose of this PhD project is to analyze and design low-profile low-cost wide-scan antenna arrays with grating lobe suppression capabilities for 5G mm-wave applications and ensure their safe coexistence with other communication systems. The concept will be validated by prototypes.
