A Novel 5G Antenna Design using Metamaterial

Design of patch antenna with microstrip feedline with single layer metamaterial array operating at 5.5 GHz for 5G cellular system is presented. This proposed antenna size of 25.2 × 18 mm² is fabricated using FR-4 substrate sized 65 × 65 mm² having 4.4 relative permittivity with 1.6 mm thickness and powered by 50 Ω microstrip feed line which shows good impedance matching. The electromagnetic (EM) simulation software is used to simulate the proposed 5G antenna. The designed antenna achieves a return loss of ≤−10 dB in operating frequency from 5.41 to 5.51 GHz, and gives resonant frequency at 5.5 GHz with a return loss of −31.57 dB. The measured gain of antenna is 6.94 dB at 5.5 GHz, and 7.04dBi representing its peak gain at 5.45 GHz. Investigated frequency domain characteristics show the performance of the antenna. The designed metamaterial based antenna can be easily incorporated with microwave circuits, making it cost-effective to manufacture. For 5G communication systems investigated radiation characteristics of the proposed antenna shows its suitability.
