In this paper we introduce an antenna that has two feed ports and is suitable for providing diversity signals in compact wireless communication handsets. The design is based on merging a monopole and a λ/4 slot antenna together to give a single compact antenna structure for external use on wireless handsets. Experimental results are presented for designs that operate at 2.4 GHz and include radiation patterns, S-parameters, and signal correlations between ports. It is demonstrated that signal cross correlations between the feed ports of less than 0.1 in typical wireless environments at the handset are possible
