Planar Antenna Design for Long Range Radar Applications

This paper describes the design of a high gain planar antenna on lossy substrate for use in long range radar applications in the 24 GHz ISM band. This is significant since most current vehicle radars operate in the 77 GHz frequency band, but as technologies for lower frequencies are less, the system should be cheaper. The paper discusses requirement in the design evolution from prototype to integrated system and uses the overall radar cost as a design parameter. Lastly measured results are presented and an indication of how the design is incorporated into the overall system is given.
