This paper discusses the design, analysis, and development of a large Ka-band slot array for digital beam-forming application. The array consists of 160 times 160 elements in 16 subarrays for producing 16 digital beams in the receive mode. Infinite array mutual coupling model has been employed in the design and analysis models. Challenges posed in meeting the pattern and return loss specifications...
Through this study, the usefulness of two forms of impedance match tuners, a) plain sheath cover, and b) patch-array cover, for FPAs has been ascertained. This work thus marks an inaugural effort towards the impedance matching of FPAs, especially for the lower frequency bands, in which the problems associated with the increased severity of mutual coupling losses have been of primary concern. It has...
A novel dual-polarized microstrip patch array with a low-loss hybrid feed network suitable for X-band polarimetric airport surveillance radars (ASRs) is presented. A waveguide feed is used to excite a number of linear subarrays consisting of aperture-coupled microstrip cross-patch elements connected in series. The microstrip radiating part implements the dual polarization capability with low cross...
