“…The high bandwidth requirements of such applications are beyond the capacity of the already congested conventional wireless bands and a migration to higher frequency bands supporting greater transmission bandwidths-such as the millimeter-wave (mmW) region-is necessary [1][2][3][4].…”
Abstract:We demonstrate W-band wireless transmission over distances covering both indoor and building-to-building scenarios with a setup of reduced complexity in the RF domain, employing a passive wireless transmitter and envelope detection at the receiver.
“…High fabrication accuracy has been achieved without using any specialized surface treatment equipment. A literature survey shows that in, 9–16 traditionally for W‐band applications, high‐gain antennas are realized by waveguides, leaky wave structures, slotted wave profiles, lensed antennas or multilayer printed circuit board (PCB)‐based microstrip patch arrays 17–25 . Similarly, an 8 × 8 slot array antenna fed by a compact hybrid feeding network in W‐band is proposed in 26 .…”

SummaryThis article demonstrates a novel type of series‐fed planar antenna array for a W‐band (70 GHz) application. The proposed architecture is a 5‐element antenna array with 10 numbers of gap‐coupled parasitic patches in microstrip configuration over a thin, flexible and bio‐compatible substrate named LCP (liquid crystal polymer). A detailed design methodology with all fabrication constraints has been elaborated on here. Full wave analysis of the whole structure has been carried out in the FEM‐based 3D electromagnetic (EM) solver ANSYS HFSS Suite V.19.2. Parametric simulations were studied to achieve the optimized values of all design parameters. Further, an empirical electrical equivalent circuit model is proposed for the antenna array, and it was validated with the simulation results obtained from the FEM solver. Two prototypes have been fabricated, and measurements were carried out to fetch all the designed antenna parameters. The proto version of the antenna offers peak directive gain of about 19 dBi with better than 22 dB of return loss and 80% radiation efficiency for the frequency range of 67–85 GHz. Experimental and simulated results closely match each other. Small deviations are attributed to practical imperfections incurred by fabrication tolerances, measurement inaccuracies, testing, assembly‐related issues and so forth. Finally, the current research work is compared with the recently reported literature.
