A novel compact multiband diversity antenna system appropriate for integration onto space-limited devices ispresented. It comprises three pairs of printed fractal Minkowski and Koch monopole antennas which resonate in the1.67–2, 2.3–2.56 and 4.55–5.55 GHz bands, respectively, supporting thus a large variety of wireless technologies for mobileand wireless local area networks (WLANs) applications. The operational characteristics of the antenna system wereextracted by simulation using a method-of-moment- (MoM-) based electromagnetic field solver. The diversity performancein a uniform multipath environment under the maximal-ratio combining (MRC) scheme is also evaluated for the two extrememodes of operation, that is, when all three antenna pairs operate simultaneously (worst case) and when only one pair is active while the others being open-circuited (best case). The calculated effective diversity gain (EDG) for the worst/best caseis 5.8/6.4, 5.8/7.2 and 7.1/7.5 dB for the 1.8, 2.4 and 5.2 GHz frequencies, respectively
