Abstract
A compact broadband millimeter wave antenna for intelligent transportation (ITS) application is proposed in this paper. This antenna uses coplanar wave guide feeding technique for broad bandwidth. The proposed antenna works at 79 GHz resonant frequency having a large bandwidth of 78.2 GHz. The measured gain of the antenna is 17.5 dBi. The proposed antenna is very suitable for short range radar (SRR) application and 5G technologies.
Highlights
Intelligent transportation system (ITS) is important part of human life and country
ITS have many applications lies in millimeter-wave frequency range like automotive radar applications and enabling wireless technologies
Automotive radar application is divided into two part like long range radar (LRR) and short range radar (SRR)
Summary
Intelligent transportation system (ITS) is important part of human life and country. It supports human economy and helps in running of country. A 79GHz millimeter wave automotive radar front–end with monolithic microwave integrated circuit (MMIC) technology having bandwidth of 9.05GHz and gain of 6.5dBi is discussed in [7]. A 77 GHz frequency modulated continuous-wave (FMCW) radar system having bandwidth of 6 GHz and gain of 10 dBi is discussed in [9]. A 79 GHz patch antenna array for short range radar system having bandwidth of 9.6 GHz and gain of 14.5 dBi is discussed in [11]. A 77 GHz millimeter wave technology for automotive radar sensors having bandwidth of 4 GHz and half power beam width gain of 5 dBi is discussed in [17]. A microstrip grid array antenna for millimeter wave frequencies having centre of 60 GHz and bandwidth of 5 GHz with gain 14 dBi is reported in [20].
