Wideband MIMO Antenna Array Covering 3.3–7.1 GHz for 5G Metal-Rimmed Smartphone Applications

A Tunable Multiband LTE Antenna for Metal-Rimmed Smartphone Applications

In this paper, a tunable multiband LTE antenna is designed for metal-rimmed smartphone applications. The antenna only uses a broken metal ring, which comprises an IFA (Inverted-F antenna) section and a parasitic section, and generates three resonant modes through this layout for the feeding point and shorting point. In addition, loading a matching circuit at the feeding point and a RF switch at...

A New Compact Ultra-wideband Linear Antenna Array for Target Detection Applications

This paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (UWB) wireless communication and target detection applications, respectively, operating in the frequency span of 3 GHz to 11 GHz. A prototype was fabricated and then measured based on optimal parameters. The results of reflection coefficient (S11) and radiation patt...

Compact massive MIMO antenna array for small 5G base stations

A WIDEBAND PRINTED MONOPOLE ANTENNA FOR 2.4-GHz WLAN APPLICATIONS

A planar monopole antenna suitable for broadband wireless communication is designed and developed. With the use of a truncated ground plane, the proposed printed monopole antenna offers nearly 60% 2:1 VSWR bandwidth and good radiation characteristics for the frequencies across the operating band. A parametric study of the antenna is performed based on the optimized design, and a prototype of th...
