Conformal Antennas

Use of 60 GHz radar with conformable antennas for object detection

In addition to the networking of machines and processes, the digitalization of production is, above all, based on high-performance sensor technology. In order to optimize the production process and increase productivity, existing machines must be retrofitted with high-performance sensor systems. However, a rapid equipping of machines with sensor systems adapted to the ambient conditions is still a problem. As a rule, the electronics are newly built for the respective application.

With the help of a modular sensor system, it should be possible to assemble complete sensor systems for specific applications cost-effectively and in the shortest possible time. The selection of modules from the fields of sensor technology enables, for example, the measurement of acceleration, temperature and pressure.

The system also allows very specific sensors to be integrated into the modular system and made usable.

Solution

On the basis of a PI-Flex technology specific radar modules with 24 GHz and 60 GHz are developed in this project, which in turn are used for conformal antennas. The radar module can detect movements and objects in a range of 360° around the sensor.

Application scenarios are e.g.:

  • Detection of workpiece positions
  • High-precision level measurement
  • tool recognition

Technological Set-up

Signal processing, PLL, RF front-end and flexible antennas were integrated into the 24 GHz radar module. Two ultra-thin 24 GHz transceiver IC with a thickness of only 20μm were embedded in the module for this purpose. The input and output signals are connected to 4x4 slot-compliant antenna arrays.

A special feature is the movable antennas for flexible alignment of the antenna transmission plane. The sensor modular system and the radar system provide a universal, rapidly deployable sensor system for the industrial sector. It enables companies to carry out flexible measurement tasks and thus drive forward digitization in the production environment.
