Abstract
The invention hereof is one kind of antenna, consisting of one substrate, one feeding network, and one layer of slot spirals. The two surfaces of substrate are conducting layers. The feeding network is made of microstrip lines and fan-stubs on the first surface. There are two feeding points of class 1 near the two fan-stubs, respectively. Another feeding point is used as the signal input/output. Two slot spirals are formed on the second surface of the substrate. Two fan-slots near the ends of slot spirals are designed as the feeding points of class 2, with one fan-slot matching one fan-stub on the opposite side. The fan-stubs and fan-slots form the transitions to relay the signals between the slot spirals and the feeding network.
