The design of a wideband diplexer integrated with a 16‐slot Continuous Transverse Stub (CTS) antenna array is presented. The diplexer‐antenna array module covers the whole WR34 band. The Tx and Rx bands cover 21.7–26 and 27.5–33 GHz ranges, respectively. The diplexer is designed to have a 100 dB attenuation in the stopband and 40 dB isolation between the channels. The antenna array has a high gain, between 26.9 and 31 dBi, at the lowest and highest frequencies. For the preliminary exploration of monolithic metal 3‐D printing of complex geometry integrated RF front ends, two prototypes were manufactured in AlSi10 Mg. One‐piece fabrication eliminates complicated assembly, enhances reliability, and reduces weight, which is more desirable for space applications. Due to several factors, namely, an unpolished inner surface and imperfect printing quality, the diplexer had a poor measured performance. The measured results of the antenna array had a relatively better agreement with simulations. Although, the realised gain was affected by the much lower effective conductivity of the unpolished 3‐D printed material. Hence, the measured realised gain was between 27.8 and 30.9 dBi in the 29–33 GHz range.

“…However, on the consideration of wideband channels, it is common to see configurations that utilize lowpass filter techniques to allow for a wide lowpass response while the upper-ranged filter response is provided by a single bandpass or highpass filter [16], [17], [18]; in this scheme, the device often becomes limited to operate as a diplexer due to the frequency region of interest being covered by the combination of lowpass/highpass responses. Albeit, this operational limitation can be overcome by the clever routing of multiple diplexers and power dividers and can be used to achieve wideband operation -for example in [19] -but comes at the cost of size and optimal electrical performance.…”

A novel wideband multiplexer is introduced as a communications equipment solution in order to provide simultaneous operation of satellite and terrestrial services in the dedicated K/Ka frequency bands (passbands ranging from 19.5 GHz to 30.5 GHz). Advanced RF filtering techniques are applied in order to accommodate a compact multiplexer design while maintaining low insertion loss and high rejection demands up to 33 GHz. Due to the overall wide bandwidth and the demanding requirements for the assigned three operational bands, different filter types have been employed. Thus, the multiplexer considers the combination of filters with rectangular, evanescent combline, and conductor-loaded resonator types. The multiplexer relies on the direct branching approach, i.e., all filters are connected to a central (star-junction) waveguide branching region. This region exhibits a reduced waveguide size to suppress interference by higher order modes. For a verification of the approach, WR34 waveguide interfaces have been considered at all ports for prototype design, however, the design can be well adapted for integrated equipment solutions with associated direct interfaces. Accurate coincidence of analyzed and measured performance of the prototype demonstrates the validity of the special approach. Moreover, additional simulations are provided as an outline for terminals with specific industry demands.

“…The reported CTS arrays are usually fed by coplanar waveguides, coaxial waveguides, or parallel plate waveguides, in which the parallel plate waveguide CTS antenna-adopted all-metal structure may have high-power handling capacity and wide bandwidth [27][28][29][30][31][32]. At the same time, the antenna can also have good conformal characteristics and beam-scanning ability [33][34][35][36][37]. In light of the above advantages, the CTS array has broad application prospects in the HPM field.…”

A continuous transverse stub (CTS) array antenna with broad bandwidth and high-power handling capacity is proposed in this paper. The technologies of multi-step impedance matching and T-shaped electromagnetic band-gap (EBG) loading are utilized, which improved the antenna operating frequency bandwidth. An H-plane lens horn is used to feed the CTS array. As a result, a good bandwidth capability of more than 32% is achieved, with a gain variation less than 3.0 dB. The measured sidelobe level (SLL) is below −18 dB in the entire frequency range. Moreover, the power handling capacity of the antenna is more than 80 MW and can reach the GW level after arraying, which indicates that this antenna has application potential in the high-power microwave (HPM) field.
