An ultrawideband (UWB) integrated filter antenna (IFA) with enhanced selectivity is proposed. A circular radiating patch is electromagnetically coupled to a UWB filter. The design provides a fractional bandwidth of 109.5% covering the entire UWB region (3.1–10.6 GHz). The peak gain of the IFA varies between 3.0 and 4.0 dBi in the desired band with efficiency of more than 90%. The gain of proposed structure is same as that of a reference standalone monopole antenna in the desired frequency band, with a decrease beyond the cut‐off frequencies. The subsystem described in this article is compact, as it does not involve any additional line to integrate the antenna and filter. © 2017 Wiley Periodicals, Inc.
