“…A sheet-like waveguide (free access mat) that is easy to manufacture and can excite the waveguide with an arbitrary antenna has been proposed [23]. In this paper, we describe the electromagnetically coupled ribbon wire interconnect used to cross the line which becomes the basis of this waveguide [24]. We describe the characteristics of one -dimensional and two -dimensional line using this structure.…”

This paper describes a sheet-like transmission line for constructing a short-range wireless communication system using flexible materials such as clothing. As a new application of wireless communications, it is desired to construct a Personal Area Network (PAN) and a sensor network with a short distance communication area of about 1 m to 2 m. For such applications, a waveguide of a new structure is required which can exchange information at an arbitrary place on the waveguide, which has a flexible structure and limits the area for wireless communication. Therefore, by disposing the microstrip type resonators two-dimensionally with a two-layer structure and electromagnetically strongly coupling the resonators, the electromagnetic waves are confined well within the transmission line, and the antenna of the wireless device resonator is arranged. Furthermore, by constructing this transmission line with a sheet-like flexible wearable material, the transmission of both information and power can be performed through a thin flexible transmission line for the wearable network.

“…That is the reason why the usage of this antenna type is especially interesting for integrated millimeter-wave (mmW) radars. At high center frequencies the antennas become small enough to make packaging solutions similar to the one presented in [3] possible. Also, feeding with a group of surface wave launchers gives the possibility to expand the beamforming in a second dimension [4].…”

This paper presents three different kinds of planar holographic antennas optimized for the usage in FrequencyModulated-Continuous-Wave(FMCW)-Radar systems. The antennas use different kinds of surface-wave modes (TE-and TMmodes), created by planar surface-wave launchers. Due to these feeds the antennas are very well suited for integration into millimeter-wave-systems. The radiation performance is calculated on the basis of holographic theory and the results are verified by full-wave simulations and measurements. Bidirectional radiation of the TE0-antennas is avoided by using Artificial-MagneticConductor (AMC) structures as antenna reflectors. This novel approach allows a holographic antenna with great integration qualifications and a highly directive and frequency-scanning main lobe and is compared with the also unidirectional TM0-mode antenna.

“…The idea of the EU funded project SUCCESS [20] is the realization of a complete RF radar frontend on a single chip combined with high efficient off-chip antennas [13], [14], [15] since the directivity and efficiency of on-chip antennas is in general limited due to the high permittivity semiconductor substrates [9]. A low-cost packaging solution is aspired by using standard QFN packages [16], [17], [18], [19] for the complete System in Package approach in which no RF signals have to be routed through the lead frame of the package.…”

“…A low-cost packaging solution is aspired by using standard QFN packages [16], [17], [18], [19] for the complete System in Package approach in which no RF signals have to be routed through the lead frame of the package. By using a flipchip or compensated bond-wire technology [10], [12], [13] for the chip-antenna interconnect, this low-cost package becomes an attractive solution also for millimeter-wave systems above 100 GHz. There are many other research groups investigating packaging solutions at this frequency ranges since the package design becomes a challenging task in realizing millimeter wave frontends.…”

This paper shows a SiGe single chip radar sensor with high efficient LCP off-chip antennas integrated in a standard QFN package at a center frequency of 122.5 GHz. The millimeterwave interconnect is performed by a CPW bond-wire connection with subsequent matching network. For demonstration purposes a complete baseband processing and RF unit is implemented on a PCB and integrated in a plastic housing where a focusing HDPE lens with a directivity of 30.7 dBi for gain enhancement can be connected. Distance measurements in a real world scenario are performed from 0.4 -18.25 m and 0.6 -14.5 m for a metal plate and a wooden plate, respectively. Additionally, a velocity measurement from 0.5 -5 m/s in the laboratory is performed.
