Abstract :

Building upon 4G LTE, 5G NR establishes the foundation for enhanced mobile broadband, including more capacity for wireless users, improved links among users (less lag time and network loss), and enhanced data rates. n38 (2600 MHz), n48 (3500 MHz), and n78 (3500 MHz) 5G NR bands are among the most commonly tested and deployed 5G frequency bands due to their relatively common availability. Dual-band or multi-band antennas are the key requirements of 5G coexistence with 4G. Since slots make patch antennas smaller and more low-cost, slot-patch antennas are extremely attractive to be used in 4G/5G dual-band or multi-band applications. In this paper, we have demonstrated a dual-band 4G LTE/5G NR slot-patch antenna for 2.6 GHz (for both 4G LTE and 5G NR) and 3.5 GHz (for 5G NR) frequency bands, and successfully verified its performance experimentally. A very good agreement can be seen between simulations and experimental results.
