Printed monopole antenna with tapered feed line, feed region and patch for super wideband applications

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.
