Ultra-wideband Sensor Antenna Design for 5G/UWB Based Real Time Location Systems

This paper presents a compact wideband (WB) sensor antenna design for Fifth generation mobile communication network (5G) or UWB based real time locations systems (RTLS). The proposed design is inspired from sleeve dipole structure. This sensor antenna consists of wideband antipodal sleeve (WAS) dipole and sleeve monopole, connect with same feedline. The advantage of antipodal configuration lies in its capability of feeding without any matching balun. So, the proposed antenna is printed on both sides of F4BM350 substrate for ease of feeding. The upper wing of WAS antenna is connected to the inner core of the SMA connector and the back of the antenna is connected to the outer conductor of the SMA connector. This antenna covers a bandwidth ranging from 5.64 - 7.25 GHz with Omni-directional radiation characteristics. A prototype of antenna was fabricated for measurement. The measured results are consistent with the simulated results. Moreover, this antenna can be used as a sensor antenna design for 5G or UWB based real-time location systems, and further can offer applications such as smart parking, localization and positioning.
