A novel and compact super wideband (SWB) exponentially tapered feed region and patch printed monopole antenna is proposed. This antenna is fed by a 50‐Ω triangular tapered feed line. The antenna operates over a bandwidth of 2.5–80 GHz with a return loss of 10 dB or more. The dimensions of the proposed antenna are 40 × 30 × 1.6 mm 3 . An exponential curve is employed in the feed region and a triangular tapered feed line is used. The ground plane feed gap is optimised to 1.3 mm. The proposed tapered monopole antenna has demonstrated an ultra‐large bandwidth with satisfactory radiation properties. Two particular antennas are examined, one with a rectangular feed line and another with a triangular tapered feed line. The performance of the antenna in frequency domain is investigated, and a good agreement is achieved between the simulation and experimental results. In addition, the time domain characteristics of the proposed antenna are evaluated experimentally. This antenna can be used in ultra‐wideband or SWB applications.
