“…The RF energy received by the antenna should be delivered to a single rectifier. Hence, the challenge is to design a single feed, wide-beam, the antenna for efficiently collecting the electromagnetic waves from wide area coverage [1][2][3][4][5][6]. The wide beam CP antennas have been proposed in Refs.…”

ABSTRACT-The radar cross section (RCS) of passive calibration targets is relatively low, which leads to a commensurate increase in the uncertainty of the radar's calibration. To address this deficiency, an active radar calibration (ARC) target was developed, which was mounted on a small remote controlled tri-copter and used for radar calibration. Results are presented for this relatively small, light weight and cost effective airborne ARC, which is suitable for the calibration of a ground to air RCS measurement system. The static RCS characteristics of the airborne ARC target were measured in a compact range and compared to outdoor measurements with the ARC target mounted on the tri-copter. The airborne capability of the calibration target was used to reduce the effects of multi-path and clutter.

“…Although Vivaldi antennas have been extensively used in many applications, especially in ultrawideband systems [5][6][7][8], the original layout has suffered from several design problems mostly related to poor and inconsistent gain, limited operational bandwidth and large dimensions.…”

Abstract-This paper presents a novel low-profile antenna with a broadside radiation. The proposed design strategy consists in modifying the layout of a classical Vivaldi antenna, thus resulting in compact dimensions and a broadside radiation pattern. Two different ways of implementing the proposed design approach are presented and discussed. More specifically, experimental data referring to two prototypes on a FR4 substrate with an operating frequency of 2.45 GHz are reported. The first layout has approximately the same dimensions of a Vivaldi antenna and a directivity of about 7 dBi, the second one has more compact dimensions (the dimensions are smaller than the ones of a standard patch antenna) and a directivity of about 5 dBi.
