Abstract

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
