This paper presents phased-array efforts at X to Ka-band based on highly-integrated silicon core chips. The work shows that it is possible to build advanced phased-arrays using SiGe chips at each antenna element. The phased-array is constructed on a single printed-circuit board which reduces the cost by a factor of 10x. This will revolutionize X, Ku and Ka-band phased arrays by making them the preferred...
This paper presents several phased-array efforts at X and Ku-band based on highly integrated silicon core chips. The work shows that it is possible to build advanced phased-arrays using SiGe chips coupled with GaAs LNAs at each antenna element for low noise operation and high G/T, or GaAs PAs for higher radiated power per element (if needed). The phased-array is constructed on a single printed-circuit...
In this paper, the concept of a current sheet array (CSA) is expanded to design a broadband bowtie-shaped antenna array. The present approach has the potential to achieve a 7∶1 bandwidth over the VHF and UHF frequency bands with wide-angle beam. A 3 by 3 array of overlapping bowtie-shaped elements, with center feeding, was simulated. Printing was carried out on both faces of the dielectric slab and...
