“…-directed double ridges are used inside parts (I), (II), and (III) to achieve the broadband characteristics, to lower the cutoff frequency, and to suppress higher order modes, respectively, in the three parts. A similar design of parts (I) and (IV) was presented in [3]. As shown in Fig.…”

In this letter, we designed and fabricated a broadband probe with a double-ridged waveguide for broadband near-field measurements. An exponentially tapered ridge in the rectangular waveguide and a novel waveguide transition were used for broadband impedance matching and suppression of higher order modes. The probe has broadband characteristics and its measured impedance bandwidth is approximately 123% (4.17:1) in the range 12.0-50 GHz for standing wave ratios (SWR) 3 0. The peak radiation gain range and nominal radar cross-section (RCS) are 5.7-14.3 dBi and 30 dBsm, respectively. The performance of this probe was verified using the measured results and is in good agreement with the simulated results.Index Terms-Antenna measurement, broadband probe, double ridges, near-field, planar near field (PNF) measurements.

“…Since invented in the 1950s, the ridged horn antennas (RHAs) have been drawing attention from worldwide for its ultrawide impedance bandwidth, simple structure, and high power capacity [1][2][3][4]. Hence, the RHAs have been widely used in electromagnetic compatibility testing systems, phased array radars, biology imaging systems, and so on [5][6][7][8][9].…”

Miniaturization of wideband antennas has attracted much attention for its wide application in modern society. This article proposes a novel broadband miniaturized four-ridged horn antenna (FRHA) with high gain operating from 2.6 to 8.4 GHz. By filling the FRHA with the epoxy-laminated glass cloth board, the side length of the aperture realizes 48% reduction comparing to a traditional ridged horn antenna. The cuboid-shaped polyethylene lens provides good impedance matching between the antenna and the air at low frequencies and decreases the aperture phase error at high frequencies, which optimizes the radiating characteristics in the whole operating band.
