Substrate Integrated Coaxial Line Based Continuous Transverse Stub (SICL-CTS) Array Antenna for 5G Base Station Applications

In this paper, a coaxial continuous transverse stub (CTS) array antenna using substrate integrated coaxial line (SICL) is proposed, to address the antenna design requirements of low loss, high performance, and compact size for millimeterwave applications. Different from conventional CTS antennas, the proposed SICL-CTS array antenna consists of SICL for transmitting TEM waves and parallel metal plates for radiation. A SICL-CTS array antenna with four elements is designed to verify the concept. From the simulated results, it can be seen that the reflection coefficient is below -10 dB from 19.64 GHz to 24.17 GHz, and the peak gain is about 6.8 dB at 20 GHz with the radiation efficiency of 94.34%. Moreover, the proposed array can maintain a ominidirectional pattern within a broadband performance. Due to the wide bandwidth and ominidirectional coverage ability, the presented SICL-CTS array antenna is a good candidate for 5G base stations.
