Abstract
- An eight-antenna array with wideband operation for future 5G New Radio mobile devices is studied. Each array element is composed of an inverted-F antenna with shorting branches and parasitic elements. The driving element (monopole structure) and the shorting element (inverted-L branch and inverted-C branch) enable the antenna to obtain multiple modes, whereas the parasitic element, open slit, and stub can improve the impedance matching. The 6 dB impedance bandwidth of the proposed eight-antenna array can completely cover the 5G Sub-6 GHz NR frequency Bands n77/n78/n79, which include the 5G band of U.S. (3.55–4.2 GHz), China, EU, and Japan (3.6–4.2 GHz and 4.4–4.9 GHz), as well as the LTE Band 46 (5.15–5.925 GHz). From the measured results, the isolation between adjacent array elements is lower than 10 dB and its corresponding envelope correlation coefficient is also lower than 0.1. [ABSTRACT FROM AUTHOR]
