Orbital Angular Momentum (OAM) Carrying Vortex Wave generation in Dielectric Filled Circular Waveguide
Md Khadimul Islam, Arjuna Madanayake, Shubhendu Bhardwaj
In this paper, we propose a method to generate Orbital Angular Momentum (OAM) carrying vortex waves inside a metallic circular waveguide (CW). These waves feature ability to carry…
Design of Maximum-Gain Dielectric Lens Antenna via Phase Center Analysis
Md Khadimul Islam, Arjuna Madanayake, Shubhendu Bhardwaj
In this work, a method is presented to maximize the obtained gain from millimeter-wave (mm-wave) lens antennas using phase center analysis. Commonly, for designing a lens antenna,…
A Passive STAR Microwave Circuit for 1-3 GHz Self-Interference Cancellation
Udara De Silva, Sravan Pulipati, Satheesh Bojja Venkatakrishnan +2
Simultaneous transmit and receive (STAR) allows full-duplex operation of a radio, which leads to doubled capacity for a given bandwidth. A circulator with high-isolation between tr…
Xilinx RF-SoC-based Digital Multi-Beam Array Processors for 28/60~GHz Wireless Testbeds
Sravan Pulipati, Viduneth Ariyarathna, Aditya Dhananjay +6
Emerging wireless applications such as 5G cellular, large intelligent surfaces (LIS), and holographic massive MIMO require antenna array processing at mm-wave frequencies with larg…
