Abstract :
A compact aperture-coupled patch antenna designed for achieving dual-band dual-polarized radiation suitable for applications in GSM 900/1800-MHz systems is presented. The proposed antenna consists of a rectangular ring patch (for 900-MHz operation) and a notched rectangular patch (for 1800-MHz operation), which are printed on the same layer, and each patch is aperture-coupled by two H-shaped coupling slots to generate two orthogonal linearly polarized waves. By further incorporating a properly designed feed network, the proposed antenna shows good port decoupling of less than -39 dB and -34 dB for dual linear polarizations at 900- and 1800-MHz bands, respectively
