Dual-band Microstrip-to-Slot Line transition

A novel dual-band Microstrip-to-Slot Line (MSL) transition which enables for instance to feed a wide-band tapered slot antenna (TSA) is introduced in this paper. The design contains two input filters connected together with a microstrip line, this line crossing then a slot-line that feeds the TSA. The relevancy of the proposed concept is demonstrated in the design and simulation of a transition operating in the frequency bands of the IEEE-802.11b/g/a/n WLAN standard, targeting antenna design for home networking devices.
