h i g h l i g h t s• PELICAN is a MMW radar designed for perception in mobile robotics applications. • Use of FMCW modulation for easy implementation and short-range measurements.• Limitation to 2D imaging due to the use of a rotating fan-beam antenna. a b s t r a c tRobust environmental perception is a crucial parameter for the development of autonomous ground vehicle applications, especially in the field of agricultural robotics which is one of the priorities for the Horizon 2020 robotics funding (EU funding program for research and innovation). Because of uncontrolled and changing environmental conditions in outdoor and natural environments, data from optical sensors classically used in mobile robotics can be compromised and unusable. In such situations, millimeterwave radar can provide an alternative and complementary solution for perception tasks. The aim of this paper is to present the PELICAN radar, a millimeter-wave radar specifically designed for mobile robotics applications, including obstacle detection, mapping and situational awareness in general. In this first of a two-part paper, the choice of a frequency-modulated continuous-wave radar is explained and the theoretical elements of this solution are detailed. PELICAN radar is using a rotating fan-beam antenna, and the construction of 2D representations of the surrounding environments with radar data is described through simulation results. The second part of the paper will be devoted for a detailed description of PELICAN radar, as well as experimental results.

A low-cost, and broadband 60 GHz microstrip Yagi array antenna is presented. It consists of rectangular microstrip antenna with parasitic patches. It has gain of 10.3 dB achieved at 60 GHz, a high total radiation efficiency of ~96%, and an impedance bandwidth of ~19.4%, which covers the entire unlicensed 60-GHz millimeter-wave frequency range. With these features, this antenna is suitable for wireless communication, and imaging applications.

“…D UE TO THE high atmospheric absorption of electromagnetic waves at 60 GHz [1], high-gain antennas are required to make wireless links of a few meters possible. Nonetheless, the V-band is still considered for various applications (wireless transmission of uncompressed high-definition video, wireless USB, wireless personal area networks, etc.)…”

A new single-element circularly polarized antenna for millimeter-wave applications is presented in this letter. A simple hybrid microstrip/elliptical dielectric ring resonator configuration is used to achieve a relatively high antenna gain. A reversed T-shaped coupling slot generates the circular polarization. The ring-shaped dielectric resonator is used to increase the gain and fine-tune the axial ratio (AR) bandwidth. Measurements show that an impedance bandwidth of 12% and a considerably wide axial ratio bandwidth (10%) are possible. The measured gain is maintained over 9 dB for a large portion of the operational bandwidth.Index Terms-Circular polarization, dielectric resonator antennas, microstrip antennas, millimeter-wave antennas.
