“…Various geometries have been used in the past as illustrated in Figure 2. The first designs used a basic empty box cavity (Figure 2, top left) [2,7,[25][26][27][28]. In most empty box cavities, the ridge is stepped down and extended into the cavity up to the back short.…”

Broadband double‐ridged guide horn (DRGH) antennas are extensively used in antenna measurement and electromagnetic compatibility and interference testing, especially the 1–18 GHz DRGH antenna which is widely accepted as a standard for this band. Certain deficiencies in the radiation patterns have been identified and corrected by several authors, but the use was still limited to the 1–18 GHz frequency band. The incorporation of absorber materials and lenses has resulted in horn antennas with wider bandwidths; however, this complicates the manufacturing process and restricts these designs to lower power applications. Simulated and measured results for a new 0.5–18 GHz (36:1) DRGH antenna are presented here. The wider bandwidth is made possible by a new cavity design and optimising the design of the other antenna sections to allow wideband operation without using a lens or absorber. The new design has double the bandwidth ratio and is very compact, with an aperture size of 26.4 cm × 15.2 cm; the aperture sides are less than 12% larger than the sides of the aperture of the conventional 1–18 GHz DRGH antenna (24.2 cm × 13.6 cm).

“…First, a narrow flare DRHA is designed using CST simulator and their structure and dimensions are shown in Figure 1A-C. The cavity structure design of the DRHA is similar to the previous report in Isenlik et al 3 The difference is that the cavity edge of study DRHA is rounded with a curve radius of 5 mm, where the cavity of Isenlik et al 3 (1) where x is the axial length (in mm) of the horn (along the x-axis) from the straight portion of the ridge. On the other hand, y(x) is the vertical distance (in mm) from the center of the horn on the y-axis.…”

“…gain >10 dBi). [1][2][3] In addition, the DRHA is relatively small in size when referring to its operating frequency lower than 1 GHz (wavelength, λ > 30 cm). However, metallic DRHA is bulky and relatively expensive, especially multi-DRHAs gathered as an antenna array for 5G communication applications.…”

In this letter, fused deposition modeling (FDM) was used to create a 1 × 2 array of the double ridge horn antenna (DRHA). The material used for FDM was acrylonitrile butadiene styrene. The DRHA was designed using an electromagnetic simulator and printed using FDM as well as the inner surface of the DRHA was painted with silver conducting paint. Two printed DRHA were connected together as a 1 × 2 array via a power divider. The main operating frequency of the array antenna was focussed on the range from 3 to 7 GHz. The 1 × 2 array DRHA is capable of better than −10 dB return loss, greater than 10 dBi gain, and a minimum half‐power bandwidth of 27.5°.

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.
