Abstract

This study introduces a new antenna design that combines a bow-tie slot antenna with four Linear Tapered Slot Antennas (LTSAs) on a single aperture, supporting multiple frequency bands for 5G applications. The design uses a coplanar waveguide transmission line to feed the bow-tie slot antenna, and a MIMO configuration is applied to the LTSAs in the mm-wave band. The antenna shows a bi-directional radiation pattern in the microwave range with a maximum gain of 6.70 dB, and an end-fire radiation pattern for each LTSA in the mm-wave band. The design effectively covers several microwave bands and the n258 band in the mm-wave range, covering both lower and higher 5G frequency bands. With its compact and efficient structure, this antenna is a promising solution for multi-band applications, making it suitable for various wireless communication systems. Its versatility and performance make it a strong candidate for future 5G technologies.
