Abstract

This paper aims to investigate of new phased array design and its radiation characteristics with highly-miniaturized and super-wideband (SWB) properties. The procedure of the phased array design is simple and can be directly performed on a single-layer substrate material. Its schematic involves eight diamond-ring-shaped dipoles with end-fire radiation and the arrangement of a 1×8 linear on the smartphone mainboard's edge made of RT5870 material with a thickness of 0.5 mm. The array elements are low-profile diamond-ring-shaped dipole resonators having discrete-feeding ports. the introduced array design represents a significant frequency range of 25-40 GHz covering multiple candidate bands in the 5G spectrum including 26, 28, 30, 36, and 38 GHz. Furthermore, the array elements' mutual coupling function is below-15 dB. The proposed array appears Using a simplified design process, low complexity profile, and its attractive broad impedance bandwidth, end-fire radiation mode, and stable characteristics meet the needs of 5G applications in cellular communications.
