Abstract

A new technique for designing a coplanar waveguide (CPW)-fed wideband slot antenna is presented. Broadband operation is achieved by creating a multi-resonator in a slot cavity and using a modified fork-like feeding structure. For the difference operation frequency, there are several different equivalent magnetic current paths are alternatively excited. Due to these different radiation regions, the radiation pattern, including in the end-fire or bore-sight direction, can be changed frequency-dependently. A 220% impedance bandwidth (S₁₁<-10 dB) is demonstrated. Simulated and measured results of the antenna are presented
