Band-rejected ultrawideband planar monopole antenna with bandstop-filter-like response using inductively coupling scheme

We discuss a new band-rejected ultrawideband planar monopole antenna in this paper. By utilizing two pairs of uniplanar folded-strips with an additional inductively coupling scheme, the proposed ultrawideband antenna demonstrates bandstop-filter-like response at the targeted rejection band. No via hole is required in the proposed antenna, which makes the fabrication process much simpler and cost saving. The antenna configuration, design concept, preliminary simulated results will be discussed carefully in this paper.
