Abstract

In this correspondence a small low profile multiband multi-slot MIMO antenna is proposed. The proposed patch antenna covers five bands. Band I covers 2.71–2.82 GHz, band II covers 3.73–4.64 GHz, band III covers 5.14–6.72 GHz, band IV covers 7.52–8.53 GHz and band V covers 8.66–9.41 GHz. It combines many applications into a single device by designing a single antenna that can be operated in multi-bands. The proposed antenna consists of multi-slot radiator with defected ground plane. Proposed antenna is smaller in size 15 × 20 mm2 (0.14λ0 × 0.18 λ0). It is extended to MIMO and mutual coupling is reduced in three bands (III, IV and V) using Defected Ground Structure (DGS). Mutual coupling in the first band (I, II) is minimized using a decoupling element. The proposed MIMO antenna is fabricated and tested. Simulation and measured results are found to be in good agreement.
