Abstract
AbstractAn increase of 7 GHz in the industrial, scientific and medical ISM band around 60 GHz has opened it up for many modern wireless applications such as 5G. This means that new component designs that can cater for this large bandwidth are the need of the hour. The design of a large bandwidth, completely planar and high gain novel Vivaldi antenna is presented. Being a travelling wave antenna and implemented using single metal layer make it an excellent candidate for not only Printed Circuit Board based applications but also the lossy Complementary Metal Oxide Semiconductor technology. For the first time, the feed of the antenna is integrated on the same conductor layer as the antenna itself. Using this design technique the problem of thin gap between the metal layers has been mitigated. The final measured results show that the antenna goes above and beyond ISM band with excellent matching performance from 55 to 84 GHz. A high gain of 7 dBi is maintained over a bandwidth of 57–75 GHz with a radiation efficiency of almost 80%. The results show that the design is quite suitable for integration in a millimetre‐wave transceiver system that can support high data rate applications.
