In this work, we study the coupling between plasmonic nanoantennas and semiconducting nanowire quantum dots (NWQDs). This coupling requires spectral, spatial and polarisation matching of the antenna mode and of the NWQD emission. Hence, a full characterisation of both the antenna system and the NWQDs has to be performed to determine a relevant coupling geometry.Using cathodoluminescence (CL) we investigate the relation between the CL signal of circular patch plasmonic antennas and the electromagnetic local density of states (LDOS). The successive resonances supported by these antennas are complex superimpositions of Bessel modes of different radial and azimuthal order. Applying an analytical LDOS model, we show that we can fabricate and cha...
