Implication

Experimental study demonstrates a compact circularly polarized wide-slot antenna for 5G systems, indicating robust dual-standard coverage for LTE 42 and LTE 43.

Key Points

To develop a compact, broadband circularly polarized wide-slot antenna operating across the LTE 42 and LTE 43 frequency standards for 5G mid-band applications.
Fabricated the antenna on an FR4 dielectric substrate with dimensions of 0.41λ₀ × 0.36λ₀ × 0.02λ₀.
Etched a square radiating slot with diagonally positioned ground stubs and loaded the feed line with horizontal and vertical stubs to induce two orthogonal current paths with equal amplitude and a 90° phase shift.
Achieved a measured impedance bandwidth of 16.2% (580 MHz across 3.3–3.88 GHz).
Recorded an axial ratio bandwidth of 12.2% (440 MHz across 3.4–3.84 GHz).
Observed measured gain values exceeding 2.5 dB across both target 5G mid-band frequency bands.
