Abstract

A novel multiband metamaterial (MTM) unit cell antenna loaded with split ring resonator (SRR) slots that resonates at seven bands, which are (1.91 GHz), (3.6 GHz), (6.25 GHz), and (8.69 GHz, 9.69 GHz, 10.70 GHz), and 12.33 GHz of the spectrum, making it suitable for L-band, worldwide interoperability for microwave access (WiMax), C-band, X-band downlink, and Ku-band applications, respectively, is proposed and discussed in this work. The proposed antenna has a very compact size of 14×15×1.6 mm3 with an FR4 substrate. The simulation results show that the presented antenna attains a reflection coefficient of less than -10 dB (S11 -10 dB) and a radiation pattern across all operating bands. In addition, the suggested antenna provides good gains over the resonant frequency signals with an average of 6.75 db. The antenna simulations and parametric studies have been done using both computer simulation technology microwave studio (CST microwave studio) and high frequency structure simulator (HFSS) to confirm the obtained simulation results.

Abstract

The aim of this paper is to propose a four-element frequency-reconfigurable antenna array operating at 38 GHz and 60 GHz for 5G applications. The proposed structure integrates three radiating elements into a single patch, enabling compactness and improved performance. The antenna achieves dual-band reconfigurability with gains of 12.65 dBi and 15.54 dBi at 38 GHz and 60 GHz, respectively. Excellent impedance matching is obtained, with S11 values of -51.82 dB and -33.79 dB at the two resonant frequencies. Frequency switching is controlled through positive–intrinsic–negative (PIN) diodes embedded in the ground-plane slot. The antenna design was modeled and validated through full-wave simulations using computer simulation technology (CST) studio suite.
