“…It is worth mentioning that the substrates are characterized by the manufacturer only up to 10 GHz and not in the millimeter-wave frequency range. Thus, it is most likely that the actual permittivities are different than the values reported in the data sheet [9]. Different simulations have been carried out to take into account possible different values of the relative permittivities.…”

In this paper the design and the implementation of a cavity antenna array in PCB technology for automotive radar applications is presented. The array consists of four cavity antennas fed by a microstrip-line feeding network and H-shaped coupling apertures in the ground plane. Simulation and measurement results show that the proposed structure is a suitable candidate for the integration in automotive radar sensors.

“…The transition between both PCBs is realized by a PCB-to-waveguide transition using a coplanar patch radiating in the Hplane of an WR10 waveguide, cf. [32]. The transition is available in two versions, one for down-and one for forward-facing antenna arrays.…”

Modern consumer and industrial unmanned aerial vehicles (UAVs) are easy to use flying sensor platforms. They offer stable flight, good maneuverability, hovering, and even waypoint flights in autopilot mode. For stabilization and localization sensors such as internal measurement units (IMUs) including gyroscope and accelerometer, barometric sensor, and global navigation satellite system (GNSS) are used. To sense the direct environment of the UAV, for instance for collision avoidance or fully automated flights, additional sensors are needed. State-of-the-art combinations of infrared sensors, ultrasonic sensors as well as vision based sensors (monocular and/or stereo vision) capture the close vicinity. Using radar sensors is advantageous, as they are able to directly sense range and velocity and are not prone to lighting conditions and contrast. With the help of a multi-channel radar, the angular information can also be extracted. UAVs can lift a considerable payload with respect to their size. All these characteristics combined with radar sensors make them a promising tool for a large variety of applications.

“…For the reflection coefficient measurements, a standard GSG-probe transition was used. For the radiation pattern measurement, the waveguide transition from [14] was used on the power distribution layer. Hence, two different PCBs were manufactured to measure the reflection coefficient and the antenna diagram.…”

A wideband planar microstrip grid array antenna is presented. The antenna is realized on a standard Rogers RO3003 substrate. It is fed using two centrally located microstrip vias through a ground aperture. Measured results show a 12% S11 <-10 dB bandwidth and a maximum gain of 17 dBi. Using a variable microstrip line width, a side-lobe suppression of at least -12 dB between 77-85 GHz is measured. The antenna can be used in short and medium range operation for automotive radar.
