Small broadband monopole antenna having perpendicular ground plane with electromagnetically coupled feed
A small broadband monopole antenna having a perpendicular ground plane with an electromagnetically coupled feed is provided. The small broadband monopole antenna may be realized as a small antenna having a size of 0.085λ0×0.085λ0×0.085λ0 by positioning a folded strip line under a shorted square disc. A resonance of the shorted square disc may be coupled to a resonance of the square folded strip line so as to form a wide bandwidth of about 36.6% of a central frequency of 2.313 GHz based on a VSWR≦2. Also, rectangular slits may be inserted into the perpendicular ground plane to improve a distortion of a radiation pattern that forms on the perpendicular ground plane so as to reduce a backward radiation by 3 dBi or more. The small broadband monopole antenna exhibits a forward radiation pattern similar to that of a general monopole antenna and has a gain of about 2.6 dBi within a bandwidth.
