Özet:

 

A planar 2×2 and 4×4 multiple-input multiple-output (MIMO) antennas are designed and analyzed in this study. The individual antenna elements that form the MIMO structure are located perpendicular to each other in order to facilitate polarization diversity. Except a notch band at 4.3 GHz, the 2×2 antenna nearly covers the entire 2.41-31.4 GHz frequency band. It is similar for the 4×4 antenna that has tri-band characteristic, where the impedance bandwidth (|S_11 |≤-10 dB) values are determined as 1.4, 10.05 and 16.26 GHz. Beside these high bandwidth results, both MIMO antennas have perfect isolation characteristic which is important to prevent coupling in MIMO systems. The proposed MIMO antennas are convenient to be used in all S (2-4 GHz), C (4-8 GHz), X (8-12 GHz), Ku (12-18 GHz) and K-bands (18-27 GHz). Furthermore, omnidirectional radiation patterns are observed at the resonance frequencies, and the reported 2×2 and 4×4 antennas have compact sizes of 80×40×1 mm3 (64.5λ×32.25λ ×0.8λ) and 80×80×1 mm3 (64.5λ×64.5λ ×0.8λ), respectively.
