TLDR
In this article, a model which allows prediction of element gain and aperture efficiency of the feed/reflector system is presented, and the predictions are in good agreement with experimental results, showing that TSA arrays used in multibeam systems with small beam spacings are competitive in terms of aperture efficiency with other more standard types of arrays incorporating waveguide type elements.Abstract:
A class of feed antennas and feed antenna arrays used in the focal plane of paraboloid reflectors and exhibiting higher than normal levels of cross-polarized radiation in the diagonal planes is addressed. A model which allows prediction of element gain and aperture efficiency of the feed/reflector system is presented. The predictions are in good agreement with experimental results. Tapered slot antenna (TSA) elements are used as an example of an element of this type. It is shown that TSA arrays used in multibeam systems with small beam spacings are competitive in terms of aperture efficiency with other, more standard types of arrays incorporating waveguide type elements. >read more

An ultrawideband (UWB) switched-antenna-array radar imaging system
TL;DR: In this article, a low-cost ultrawideband (UWB), 1.926-4.069 GHz, phased array radar system is developed that requires only one exciter and digital receiver that is time-division-multiplexed (TDM) across 8 receive elements and 13 transmit elements, synthesizing a fully populated 2.24 m long (λ/2 element-to-element spacing) linear phased array.
