Abstract
The paper presents the improved design of the novel circularly polarized patch antenna array operating at ISM band 24.05-24.25 GHz. The antenna array consists of 24 identical truncated patches which are serially fed through the microstrip line. The antenna is a travelling-wave array with exponential power distribution which provides very good side lobe suppression of 30 dB in the entire operating band making it suitable for automotive radar applications. Simulated axial ratio is below 3dB in the range (24.06-24.26) GHz, the antenna gain is greater than 17.2 dBi, cross polarization is better than 15 dB and return loss is greater than 15 dB in the entire ISM band.
期刊介绍：
The TELFOR Journal is an open access international scientific journal publishing improved and extended versions of the selected best papers initially reported at the annual TELFOR Conference (www.telfor.rs), papers invited by the Editorial Board, and papers submitted by authors themselves for publishing. All papers are subject to reviewing. The TELFOR Journal is published in the English language, with both electronic and printed versions. Being an IEEE co-supported publication, it will follow all the IEEE rules and procedures. The TELFOR Journal covers all the essential branches of modern telecommunications and information technology: Telecommunications Policy and Services, Telecommunications Networks, Radio Communications, Communications Systems, Signal Processing, Optical Communications, Applied Electromagnetics, Applied Electronics, Multimedia, Software Tools and Applications, as well as other fields related to ICT. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies towards the information and knowledge society. The Journal provides a medium for exchanging research results and technological achievements accomplished by the scientific community from academia and industry.
