Wideband MIMO Antenna with Neutral Line Structure

Pratiksha Pandey, Bimal Garg

Abstract


A 2×2 wideband MIMO inverted F-shape antenna is designed and fabricated. The proposed antenna structure operates in wide frequency range of 2.47-5.90 GHz (impedance bandwidth =81.95 %). The proposed MIMO structure occupies total compact area of 0.32〖λ^2〗_0 (λ_0 = highest operating wavelength). Inter-element isolation more than 10 dB and maximum gain over frequency ≈ 4.45 dBi are achieved throughout the operating frequency band of the proposed MIMO structure. To improve the coupling between radiating elements of this antenna, a novel structure of neutral line is added. An ECC is smaller than 0.1 and the diversity gain of about 10.0 dB has been achieved.

Keywords: connected ground structure, mimo, neutral line, wideband
