Hybrid optimisation algorithm and its application for pattern synthesis of planar arrays

Autor: Zhengdong Qi, Yangyi Lu, Yue Kong, Youji Cong

Publikováno v: The Journal of Engineering (2019)

A hybrid approach to the synthesis of sparse arrays radiating shaped or focused beampattern is presented in this paper. Specifically, an iterative scheme is used where the prescribed pattern response in the mainlobe peak direction is cast as a multi-

Proximity-coupled feed patch antenna array for 79 GHz automotive radar

Autor: Haiyan Tian, Changjiang Liu, Xiang Gu

Publikováno v: The Journal of Engineering (2019)

Autonomous driving is becoming a reality-but low-cost 79 GHz radar antenna technology is still imperfect. Here, the authors propose a kind of proximity-coupled feed patch antenna array. By reducing the non-linear mutual interference between the trans

Nouvelles topologies d’amplificateurs de puissance SiGe en bande Ku, optimisées en puissance, rendement et robustes au TOS actif

Autor: Coquillas, Benjamin

The improvement of the RADAR systems of the current aircraft is confronted with the two major challenges of the reduction of the areas occupied and the control of the cost. These challenges are added to the specific material constraints of self-guide

Study of the Isolation between Complementary Antennas

Autor: Robert Staraj, Lamia Sadaou

Publikováno v: International Workshop on Antenna Technology (IWAT 2020)
International Workshop on Antenna Technology (IWAT 2020), Feb 2020, Bucharest, Romania. pp.4, ⟨10.1109/iWAT48004.2020.1570616467⟩
International Workshop on Antenna Technology (IWAT 2020), Feb 2020, Bucharest, Romania

International audience; In this paper, we will focus on complementary antennas with orthogonal radiation patterns, in order to develop another type of multi-band antenna for diversity systems. The study is based on the use of monopoles and quarter wa
