The designed whole system of conformal phased array covered with QCTO lens is presented in Fig.3(a), and the conformal array antenna as well as array element structure are shown in Fig.3(b)in detail. In the practical design, the aperture-coupled microstrip patch antenna array with linear p...
plasmonic waveguides has been demonstrated in ref.22. The proposed beam-steerable POPA is a perfect candidate for the construction of such a datalink for plasmonic ICs. As the third example, the idea that improving laser efficiency with the aid of an antenna array has been successfully ...
In recent years, phased antenna arrays have gained a wider and wider popularity. Presently, the trend is to increase the efficiency of the phased array systems. In particular, there is a specific need for greater capacities and transmission speeds, which requires the design of higher performance ...
This work presents the design and simulation of phased array antenna system with MEMS phase shifters. The phase shifter is tunable in the frequency range 4–6.5GHz. The designed phase shifter is employed in four element microstrip-based phased array antenna (PAA) for generating steerable beam ...
Phased array subsystems are becoming essential in next-generation mobile communication for their ability to electronically steer antenna beams without physical movement. Previous methods for rectangular microstrip patch radiation using orthogonal modes with a 90掳 time-phase difference res...
Existing methods of producing narrow beamwidths using patch based design are analyzed for their applicability given the design restrictions. A mathematical construct of the system is then developed and used to help generate a design that is then simulated using Ansoft's HFSS electromagnetic simulation ...
The array has been numerically evaluated using a 50﹌m radio over fiber system, responsible to transmit the RF signal from the Central Office to the Remote Antenna Site. It has been used the following pieces of software: VPI Transmission Maker for optical domain simulations, Designer and HFSS ...
3dB coupler ensures equal power is fed to the antenna system while crossover maintains signal purity whenever transmission lines overlap. Phase shifter provides necessary phase shift need for beam formation in desired direction. Each of these devices is analyzed separately using ANSYS HFSS and ...
