Abstract
This paper is a work about the importance of wide frequency deviation, Δf, in linear FMCW radar applications and the design and measurement results of the antenna thought to be suitable for these applications. First, working principle of linear FMCW radar is briefly told. Afterwards, it will be mentioned about the benefits of choosing high frequency deviation in these radars such as suppressing the distortion effects caused by modulation frequency harmonics, obtaining high range resolution and providing frequency diversity. A brief design and measurement results of the antenna, which is considered for the applications of this type radar and increases the frequency deviation to 400 and 900 MHz in two different frequencies, where it is typically 100-150 MHz due to the narrowband antennas, will be presented in next part.
