“…Contactless technology is a widely recognized and applied con-cept, notably in radio-frequency identification (RFID) systems 9,10 for dynamic coupling and SIW multilayer coupling for static coupling. Different nearfield coupling technologies are being compared in this section: RFID-related examples, [10][11][12] filters in multilayer PCB, [13][14][15] and one example of cross-over in Ka band 16 The last instance functions on a comparable principle, coupling in a static multilayer SIW, operating within a similar frequency range. Despite the dynamic nature of the proposed structure, the structure with its reduced air gap distance exhibits wider bandwidth and reduced coupling loss compared to the aforementioned example.…”

A novel contactless excitation method for leaky‐wave antennas (LWAs) is proposed based on near‐field coupling between a physically disconnected input feed section and input ports of LWAs. Periodic slot‐pairs in substrate‐integrated waveguides are used to implement a plurality of planar LWAs in the Ka‐band, where contactless excitation allows switching of the input port along an antenna array without any mechanical disconnection and reconnection of coaxial connectors, thereby opening the path for mechanical switching‐based pattern reconfiguration. To demonstrate the proposed principle of contactless excitation, prototypes are shown with detailed reflection characteristics and radiation pattern measurements.

A series of fourth‐order bandpass filters (BPFs) with compact footprints, broad bandwidth, high selectivity, linear phase and notched response are proposed. The sketch of these BPFs is in accordance with the combination of the eighth‐mode substrate integrated waveguide (EMSIW) and dual‐mode microstrip line (DMML) resonators. The DMML resonator is constructed by means of metallic via‐holes and pad in the double‐layered structures. Among them, the DMML resonator can provide two transmission poles. Besides, the cross coupling is introduced through the vertical slot or fan‐shaped aperture in the dual‐layered substrates. The coupling schemes of the proposed BPFs can introduce two transmission zeros in the vicinity of operating passband, and the coupled scheme also exhibits a relatively flat in‐band group delay. Notched frequency responses have been obtained by exploiting the U‐shaped resonator and folded‐ring resonator embedded with the mixed EMSIW and DMML BPFs. To validate the conceptual design, the proposed BPFs are simulated, fabricated and measured. Both the simulation and measurement have reached to a satisfactory agreement.
