The Utilization Of Software Defined Radios For Adaptive, Phased Array Antenna Systems, Evan Fennelly

Graduate College Dissertations and Theses

The increased use of internet of things (IoT) devices will result in them being deployed

in a wide variety of environments and therefore warrant antenna systems that can be

adapted to improve link performance. Flexible communication technologies allow for

increased throughput, reliability, and improved efficiency in wireless channels. This

can be accomplished by implementing phased array antennas, among others. Phased

arrays create a beam that can be steered electronically, but are expensive to implement

given the many phase precise hardware components that need to be adjustable. A

software defined radio approach to beamforming can reduce this complexity for each

array …

Cmos Programmable Time Control Circuit Design For Phased Array Uwb Ground Penetrating Radar Antenna Beamforming, Nicholas James Reilly

Graduate College Dissertations and Theses

Phased array radar systems employ multiple antennas to create a radar beam that can be steered electronically. By manipulating the relative phase values of feeding signals among different antennas, the effective radiation pattern of the array can be synthesized to enhance the main lobe in a desired direction while suppressing the undesired side lobes in other directions. Hence the radar scanning angles can be electronically controlled without employing the bulky mechanical gimbal structure, which can significantly reduce radar system size, weight and power consumption. In recent years, phased array technologies have received great attentions and are explored in developing many …
