This contribution presents a fully self-diplexing and dual linear polarized antenna operating in the K-and Ka-band. The combination of a 30 GHz substrate integrated waveguide (SIW) slot antenna and a 20 GHz microstrip patch antenna (MPA) results in a compact dual-band design. Standard printed circuit board (PCB) technology yields a three layer assembly with a footprint of less than 7.5x7.5mm2 and a height of 0.55 mm. The circuit includes a filter which improves the inter-band isolation in the upper band from 12 dB to more than 45 dB. The-10 dB reflection bandwidth remains above 0.55 GHz and 0.75 GHz in the lower and the upper band, respectively. Because of its compactness, the proposed antenna is well suited for applications in phased arrays.
