Abstract :
A printed rectangular monopole antenna design with an enhanced, extremely wide, 30:1 bandwidth is presented in this paper. The antenna has been designed for printing on Rogers 4350 substrate with a dielectric constant of 3.48. The bandwidth enhancement is achieved by introducing a trident-shaped feed interface to the radiation patch. By the introduction of this feed interface and optimising, it was possible to the increase the 2:1 VSWR bandwidth from 0.82–7.8 GHz to 0.82–25 GHz.
