“…Advanced communication equipment is required to support future multi-use applications such as simultaneous satellite and terrestrial services [1]. Integrated systems such as these require complex solutions that are capable of combining modern high-throughput satellite (HTS) services -which rely on Frequency Division Duplex (FDD) and operate at frequencies such as 20 GHz for downlink (DL) and 30 GHz for uplink (UL) -with state-of-the-art communication networks (i.e, 5G Enhanced Mobile Broadband (eMBB)), which are based on Time Division Duplex (TDD) and assigned broad frequency bands located around 25 GHz.…”

“…In this regard, highly stringent performance requirements necessitate the pioneering of new and unconventional solutions to unlock the potential of future HTS architectures and ≥5G/6G networks, and moreover, can help to unlock other desirable benefits or applications, such as highly miniaturized designs, effective smart-jamming counter measures, and integrated multiplexing/demultiplexing antennas [1], [2], [3], [4], [5]. One prerequisite of an equipment design providing the combined FDD and TDD services is a wideband multiplexer for the combination and separation of these frequency bands while feeding a common antenna.…”

“…Each of these filter branches is connected to a common junction, which provide connection to the common feed port of the multiplexer. For equipment integration, there is no need to consider standard waveguide interfaces at the ports, i.e., they can conveniently be adapted for optimal interconnections within the equipment [1], [20]. However, for the validation of the design approach, WR34 waveguide interfaces are considered for a prototype design at all ports.…”

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.

Microwave filters are indispensable passive devices for modern wireless communication systems. Nowadays, electromagnetic (EM) simulation-based design process is a norm for filter designs. Many EM-based design methodologies for microwave filter design have emerged in recent years to achieve efficiency, automation, and customizability. The majority of EM-based design methods exploit low-cost models (i.e., surrogates) in various forms and artificial intelligence techniques assist the surrogate modeling and optimization processes. Focusing on surrogate assisted microwave filters designs, this paper firstly analyzes the characteristic of filter design based on different design objective functions. Then, the state-of-the-art filter design methodologies are reviewed, including surrogate modeling (machine learning) methods and advanced optimization algorithms. Three essential techniques in filter designs are included: 1) Smart data sampling techniques; 2) Advanced surrogate modeling techniques. 3) Advanced optimization methods and frameworks. To achieve success and stability, they have to be tailored or combined together to achieve the specific characteristics of the microwave filters. Finally, new emerging design applications and future trends in filter design are discussed.

“…Next-generation 5G/6G networks (Figure 19) will rely heavily on satellites to extend/complement existing capabilities and provide access to digital technologies to everyone everywhere around the globe. More advanced features, such as higher data rates and flexibility in traffic and service allocation, will be made possible by transitioning from transparent to fully regenerative satellite payloads [149].…”
