Metamaterial-Based Series-Fed Antenna with High Gain and Wideband Performance for Millimeter Wave Spectrum Applications

Abstract

This paper presents a high-gain, wideband series-fed antenna designed for 5G millimeter-wave (MMW) applications. The structure employs a substrate-integrated waveguide (SIW)-based power splitter and metamaterials (MMs). The power divider functions effectively at 27.5 GHz, exhibiting an impedance bandwidth from 26.9–28.6 GHz. The series-fed dipole is assembled on the SIW-based power splitter, incorporating four dipoles with varying lengths and spacing. The di-poles are connected in series on both sides, running in parallel through a microstrip line. Effec-tively combining the resonances of the series-fed dipoles and the SIW results in a broad imped-ance bandwidth, ranging from 26.9 GHz to 34.75 GHz. The design offers a gain extending from 9 to 10.5 dBi within the operating bandwidth. To improve gain performance without a substantial increase in antenna size, 11 × 6 MM unit cells have been positioned in front of the antenna. As a result, the proposed antenna achieves a maximum gain of 14.1 dBi at 30.5 GHz while maintaining an operational bandwidth of 7.85 GHz. Additionally, due to the arrangement of the MM-based two series-fed dipoles, the antenna exhibits symmetrical dual-beam E-plane radiation at ±20° at 28 GHz in the end-fire direction. The developed system was experimentally validated and demon-strated excellent agreement between the simulated and measured data.
