Non-Omnidirectional Monopoles Forming a UCA and Resulting Resolution Capability of MUSIC

This paper covers the trade-off between the directivity of monopoles over a finite ground plane forming a uniform circular array (UCA) and the resolution capability of this UCA when utilizing the MUSIC (MUltiple SIgnal Classification) algorithm. An expression for the threshold array signal-to-noise ratio (ASNRth) with respect to uniform linear arrays (ULA) has been published before by others and is extended in this contribution to a UCA.
