“…Waveguides and horn antennas are used to create low-loss fixed-beam antenna arrays [4] and printed circuit boards (PCB) with phase shifters can be implemented in the waveguide environment to create beam steerable antenna arrays [5]. Various in-line transitions from air-filled waveguide (AFWG) to substrate-integrated waveguide (SIW) [6], to microstrip line [7], and to monolithic millimeter integrated circuit (MMIC) have been presented [8], [9] to integrate radio-frequency integrated circuits (RFIC) into waveguides.…”

This paper proposes a scalable substrate-integrated waveguide (SIW) module accommodating an in-line vector modulator monolithic millimeter integrated circuit (MMIC). The SIW module is realized with low-temperature co-fired ceramic (LTCC) technology, and it can be inserted in a dielectric-filled waveguide (DFWG). The module combines λg/4-transformerbased E-plane tapering and SIWs on LTCC with the wirebonded vector modulator. The proposed active LTCC module and two passive test structures (i.e., a constant-height-SIW module and a SIW module with E-plane taperings) are manufactured and tested as in-line modules in a DFWG. The passive test structures with the waveguide-to-DFWG and DFWG-to-SIW transitions measure 3.1 dB and 4.6 dB of insertion loss on average, respectively, at the 71-81 GHz frequency range. The active LTCC module measurements demonstrate a dielectricfilled waveguide with phase and amplitude tuning capability and gain up to 17.6 dB within the same frequency range. A fourchannel mock-up module with λ0/2 channel spacing is designed and manufactured to demonstrate the scalability of the design.

“…Активно исследуются возможности скоростной передачи данных между микросхемами посредством диэлектрических волноводов (ДВ), что отражено в работах [4] и [5], а также многомодовые диэлектрические волноводы [6]. Активно начинают применяться стержневые диэлектрические антенны [7] и антенные решетки, рассмотренные в работах [8] и [9]. С 60-х годов прошлого века исследовались лучеводы или сверхразмерные полые металлические волноводы [10], которые ничем конструктивно не отличаются от обычных, за исключением увеличенных размеров сечения (рис.…”

. The present paper is devoted to the design of a new shielded metal-dielectric waveguide with low losses (less than 0.5 dB/m) and wide bandwidth for the 90–100 GHz frequency range. Various types of waveguide structures were analyzed, such as metal waveguides, oversized metal waveguides, dielectric waveguides, dielectric waveguides with a metal shield and various designs of the dielectric filling element. Estimates of loss per unit length in them are obtained. The design of a waveguide containing an oversized round metal screen and a dielectric element consisting of a plate and a rod, located in the center of symmetry of the device, is proposed. The task of creating a transition from the investigated waveguide to a standard rectangular metal waveguide is considered. It is a horn transition from a circular cross-section to a rectangular one with a length of more than 25 wavelengths with a dielectric structure continuing the dielectric element of the waveguide path. As a result of the work, the ratios of the dimensions of the structural elements of the waveguide path and the materials used were obtained that satisfy the required losses.

“…In order to feed the different dielectric antenna elements a power distribution network is needed. A hollow waveguide feed such as in [8], [9] could be an option, but it is comparably heavy and has to be assembled with individual metallic and dielectric parts. A combination of a metallic and a dielectric approach has been shown in [10], where the dielectric is electroplated.…”

This paper presents an overview of fully dielectric antenna arrays with integrated dielectric power dividers developed at Technische Universität Darmstadt as an extension of previous work. The power dividers are based on the principle of multimode interference and offer one- and two-dimensional power division in a single step, which allows the realization of small and lightweight devices. In order to prove the concept, 1 × 4 and 4 × 4 fully dielectric antenna arrays with integrated power dividers milled from Rexolite are designed, realized and characterized, operating between 90 GHz and 105 GHz. To assess miniaturization and beamsteering capabilities, three 1 × 4 arrays composed of different materials, Rexolite, Preperm L300 and Preperm L440, are compared regarding gain, size, weight and element spacing. Depending on array size and material, gain is between 12.5 dBi and 22 dBi, accompanied with sidelobe levels below - 7.5. All demonstrators are realized by milling, but the designs show the potential to be 3D printed or injection molded for large scale manufacturing.
