“…Previously, Komarov and coworkers proposed a broadband CWT with a corner transition structure implemented between a coaxial line with an inner/outer radius of 1.52/3.50 mm and a rectangular waveguide with the narrow-to-wide wall ratio or the waveguide height(b)-to-width(a) ratio b/a of 5/35 [5]. The transition structure consisted of a rectangular waveguide with an input guide size of a × b = 35 mm × 8 mm and an output guide size of a × b = 35 mm × 5 mm, and a coaxial line terminated by a disk probe.…”

“…Actual performance would be better: the bandwidth can be wider, and the VSWR smaller than the manufacturer's specifications.

We included the performance of a commercial half-height waveguide adapter by Tei Teng Wireless Co., shown in Figure 13.…”

For miniaturization, rectangular waveguides with a reduced height are often required, along with a coaxial transition for signal launching. We present a simulation-based design of a broadband transition from a coaxial cable to a rectangular waveguide with the height(b)-to-width(a) ratio b/a ranging from 0.125 to 0.375. The proposed transition consists of a coaxial probe with a cylindrical head or a disk and two symmetrically placed tuning posts. To extend the operating frequency range, three sections of the rectangular waveguide are employed with properly chosen dimensions. Design examples are presented for the WR75 waveguide transition with a b/a of 0.125, 0.25, and 0.375, having a bandwidth of 83.4%, 92.7%, and 84.4%, respectively. Compared with previous works, our design offers the largest bandwidth in a right-angle coaxial-to-rectangular waveguide transition employing the aforementioned structure.

“…In [16], a full-wave numerical modeling of a probe-excited waveguide was proposed, but the work does not encompass a design of a horn antenna. In [17], a C-band adapter for a coaxial line-torectangular waveguide transition was analysed by simulations, with no horn antenna included in the work. Likewise, a design of a Chebyshev multi-section broadband coaxial-to-waveguide adapter was proposed in [18] for the THz regime, with 0.02mm precision of fabrication but due to a multi-section design that increases the length, it would not be practical enough for an implementation with 3D printing at the S-frequency band.…”

In this paper, we propose a streamlined design and automation of a horn antenna and its rectangular waveguidebased feeder using computer simulation-based optimizations and additive manufacturing. The approach enables time-effectiveness with a holistic design of the two components, while achieving advantageous results of the antenna parameters. The approach is described in comparison to other works and the results presented and discussed on the antenna models manufactured for two midband frequencies: at 2437 MHz and 5250 MHz. The optimumsearch algorithm was able to find the parameter values that resulted in more than 25 dB improvement in S11-parameter values in comparison to the initial design based on the textbook theory. For the 2437-MHz antenna, the achieved bandwidth, using the optimized parameters, was 16.52% wide comparing to 5.14% bandwidth that was the result based on the analytical expressions. In case of the 5250-MHz antenna, the optimized antenna bandwidth reached 25.47%. The fabricated antenna gain was close to the design value.
