Octave bandwidth printed bow-tie fed partial cavity slot antenna

摘要

A partial cavity backed wide bandwidth slot antenna fed with a bow-tie feed line is proposed as a viable element for mobile communication base station applications. A novel feeding mechanism consisting of a printed bow-tie feed placed within the slot aperture and metal baffles between the slot ground plane and a grounded backplane allow this antenna to operate over more than an octave bandwidth (1.15 to 2.46GHz) with a VSWR <2.
