Abstract

This paper presents a low-profile, isolation-enhanced, multiple-input multiple-output (MIMO) antenna with a band-notch feature. The MIMO structure comprises two fractal-shaped slotted radiating elements along with a defected ground structure. Arlon AR600 is used as the substrate material. The frequency notch is obtained by etching a split-ring rectangular resonating structure into the surface of the radiating elements. An impedance bandwidth of 3.0–11.1 GHz is obtained along with a band-notch feature centered at exactly 3.5 GHz. The analysis of the frequency- and time-domain response of the proposed structure gives satisfactory results, and good agreement is observed between the simulated and measured data. The simple design and compactness along with the incorporated band-notch feature justify the applicability of the presented antenna in the ultra-wideband communication domain.
