This article is aimed to discuss a novel high directional flared quasi‐Yagi offset feed monopole UWB antenna. The proposed antenna is stamped on an FR‐4 dielectric material of dimensions 40 mm × 48 mm × 1.6 mm, which is exhibiting a permittivity of 4.4 and a loss tangent of 0.019. It operates within a frequency spectrum of 3.06 to 12.37 GHz that includes the complete FCC ultra‐wideband of 3.1 to 10.6 GHz. Maximum peak gain and radiation efficiency of this antenna are found to be 10.07 dBi at 10.4 GHz and 92.64% at 4.7 GHz, respectively. The presented antenna employs a novel structure comprising of flared elements, directors and offset feed to a planar monopole for achieving directional behaviour. Thanks to the novel technique for enhancing uni‐directional characteristics in the entire operating band. Prototype of the proposed structure is fabricated and measurement results are verified with the simulation results. A good matching is also found between them.
