“…For the frequency range starting from 0.3 GHz up to 3 GHz a size of 450 mm x 300 mm is required. The shape of the two arms is derived from Lee and Livingston [3] and further developed for best performance. The antenna feed has 978-1-4244-4968-2/10/$25.00 ©2010 IEEE and measured with sufficient S/N ratio.…”

Abstract-A planar Dual Exponentially Tapered Slot Antenna (DET SA) is presented. The DETSA is simulated and designed with the software Ansoft High frequency Structure Simulator (HFSS). The dimensions of the antenna and the exponential functions of tapered slot are also described. To verify the design, the DETSA is fabricated and measured, good impedance matching over a very wide bandwidth is achieved, measured radiation patterns of the proposed antenna are compared with the simulated one, good agreement is observed. Simulated group delay of the antenna is presented.

“…1E. This, so-called bunny-ear antenna [9], which does not require a (lossy) dielectric substrate or additional balancing feed board, represents an inexpensive and suitable candidate for the SKA project when aiming for differential technology. Obviously, the expensive and noisy feed board is no longer required if a Low Noise Amplifier (LNA) is directly attached to the antenna and is realized in differential technology (coplanar strips for instance), or if the transition to single-ended technology has been realized within the LNA.…”

Abstract-The results of a parametric study and design of an ultra-wideband dual-polarized array of differentially fed Tapered Slot Antenna elements are presented. We examine arrays of bunny-ear antennas and discuss the capabilities and limitations of differential antenna technology. As we focus on radio astronomical applications, the absence of a balancing-feed circuit not only reduces the first-stage noise contribution associated to losses in the feed, but also leads to a cost reduction. Commonmodes are supported by the antenna structure when a third conductor is present, such as a ground plane. We demonstrate that anomalies may occur in the differential-mode scan impedance. Knowledge of both types of scan impedances, differential and common mode, is required to properly design differential LNAs and to achieve optimal receiver sensitivity. A compromise solution is proposed based on the partial suppression of the undesired common-mode currents through a (low loss) balancing-dissipation technique. A fully steerable design up to 45º in both principal planes is achieved.
