Design, fabrication and test of a dual-linearly polarized wideband printed planar monopole antenna is presented. The proposed configuration consists of two orthogonal CPW-fed modified octagonal monopoles with low mutual coupling. It is developed to be used in a wearable antenna system application to probe the electromagnetic field, with frequency in the range 0.7-3.5 GHz (5:1 bandwidth), incident on a professional user. The reasonable agreement obtained between simulated and experimental results has validated the proposed design approach and provided the proof of concept.
