“…Initially, the focus was on solving the pattern deterioration problem, which resulted in several improved designs [12][13][14][15][16][17][18][19][20]. Further work included manufacturing tolerance and sensitivity studies [21,22], extending the improvements to other frequency bands [23][24][25], and improvements in performance by investigating the ridge width, ridge profile, launcher cavity, and sidewalls [26][27][28][29]. Some of the improvements also resulted in slightly wider bandwidths in the order of 20:1 and 25:1 [17,19,24,27].…”

Ever‐increasing bandwidth requirements from various industries drive the need for the ever‐increasing bandwidth of antennas used for testing. Broadband Double‐Ridged Guide Horn (DRGH) antennas are used extensively in antenna measurement and ElectroMagnetic Compatibility/Interference (EMC/I) testing. The current state‐of‐the‐art broadband DRGH antennas reported in the literature for use in measurement applications cover bandwidth ratios as large as 36:1 (0.5–18 GHz). This paper presents the design and realisation of a DRGH antenna with a 100:1 bandwidth ratio (0.5–50 GHz). To achieve such a wide bandwidth, the ridge gap, width and feed were optimised, and a novel coaxial‐to‐ridge waveguide launcher section based on a typical Vivaldi antenna was developed. Backward radiation was reduced using an absorber‐filled cavity. A prototype DRGH antenna was manufactured using additive manufacturing, also referred to as 3D printing. Simulated and measured results obtained in an anechoic chamber are presented.

“…This additional taper term is determined experimentally, and it provides a significant improvement in impedance matching for the first octave of the frequency band and has little effect elsewhere [2]. In the literature, the coefficients were determined completely empirical, however, it is possible to find out the values of the coefficients in (1) using the following equation [25]:…”

It is well known that the beamwidths of horn antennas are inversely proportional to frequency. Previous studies point to minimum ±12% beamwidth stability within a maximum of 2.5:1 bandwidth (BW) ratio. To extend this BW, a design methodology for broadband double‐ridged horn antenna (DRHA) is proposed and applied to 4.5–18 GHz frequency band. Firstly, a conventional DRHA is designed and studied to compare the beamwidth variation of wideband horn antennas. By explicitly addressing the shortcomings of conventional DRHA, DRHA is redesigned and near‐constant beamwidth DRHA is proposed using the modifications implemented on the sidewalls. The antenna utilises ridges to extend the frequency band, unlike other wideband constant beamwidth horns. The authors show that ridged horns, whose dimensions are appropriately designed and modified, can have stable beamwidths. Then, properly positioned curved pinwalls are designed to provide considerable improvement in H‐plane beamwidth constancy. Broadband double‐ridged waveguide‐to‐coaxial adapter is also designed for 50 Ω reference. The prototype is manufactured, and the measured antenna exhibits wideband characteristics with 30.9° ± 2.7° half power beamwidth in H‐plane over 4:1 BW ratio. This variation corresponds to ±8.7% beamwidth stability along with the target frequency band.

In this paper, the design, fabrication, and test of an additive manufactured double-ridged horn antenna optimized to work in ultra-wide-band frequencies is introduced. In particular, to build this antenna, the fused deposition modeling fabrication method is selected. The plastic-made device is then coated by using conductive ink. The double-ridged horn is conceived as a monolithic block. In this way, performance degradations caused by fabrication inaccuracies are minimized. A very good agreement between the simulations and the antenna measurements is demonstrated. The proof-ofconcept prototype has an outstanding operational bandwidth performance of 11.5 GHz (fc 8.25 GHz) with a gain of 6 dBi; its total weight is less than 200 gr, and the total prototyping fabrication costs are less than 10 Euro per antenna with a lead time of less than a week.
