1. Adaptive Beamforming Dielectric Resonator Antenna Algorithm With Higher Spatial Resolution Of The Electromagnetic Energy

In this project, we propose to work on the research and development of adaptive beamforming dielectric resonator antenna array (AB-DRAA) for LTE band 7 (2.6 GHz with bandwidth range 2500-2700 MHz).The proposed array will be able to perform beam-steering and null-steering simultaneously. This feature of AB-DRAA to orient its main beam towards the desired user and nulls towards the unintended users makes it an excellent candidate for 4th and 5th generation telecom networks. For example, 3G and 4G telecommunications infrastructure involve multiple transmit receive antennas where the use of such adaptive smart antennas can increase the network capacity considerably. The prototype antenna array will be highly reliable, efficient and will be designed specifically for LTE applications.
             The intellectual merit of this research emphasizes on the discovery and investigation of a new class of adaptive beamforming algorithms. In particular, the results of this work will be the first depiction of a DRA based adaptive beamforming array. This new type of adaptive array will find extensive use in: 1) Amplitude and Direction of Arrival (DoA) estimation with higher spatial resolution of the electromagnetic energy and 2) appropriate phase compensation for real-time recovery of beamformation patterns.
          The broader impact of this proposed research is to excite the interest of undergraduate and graduate students in modern research; we delineated a part of this project for enhanced undergraduate and graduate student participation under the guidance of senior personnel. The undergraduate students will be involved with the measurement and characterization of attenuators, phase shifters, power dividers, zero-phase transmission lines and phase compensation circuits. Graduate students participation in all aspects of this work (theoretical development, simulation, fabrication, characterization), is also an integral part of this effort.

  • 2. Design And Development Of Conformal Beamforming Array (CBA) For Aerial Platform

    In this project, we propose to work on the research and development of conformal beamforming array (CBA) that will be tested on a fuselage/wing portion of a small surveillance unmanned aerial vehicle (UAV) or a commercial UAV model. The traditional design philosophy is to use a planar array with the required performance and warp the array to fit the constraints with little to no consideration of the change in inter element coupling and underlying performance. The proposed CBA can also be used in passive radar for the detection of low flying objects and will be able to perform beam-steering and null-steering simultaneously.
    The proposed CBA system will be scalable (both in terms of frequency, and size of the conformal array), having adaptive beamforming capabilities (without human intervention), efficient and will be designed specifically for aerial platform structures. Moreover, the CBA developed can be used in many commercial/defense applications, for example,
    1) On the skin of an automobile for safe driving through alert messages/automatic brakes control using its beamforming capability,
    2) On a cellular base station to increase the network coverage/capacity,
    3) Access points in a broadband networks to achieve higher date rates,
    4) Body area networks, and
    5) Data transmission clothing.
