The antenna includes a lower substrate, an upper substrate stacked on the lower substrate, a radiator, which is located between the lower substrate and the upper substrate, has a rectangular patch shape in which two triangular removed parts are formed by removing opposite corners in a triangular shape, extends so as to have a predetermined width and length from one end of a hypotenuse of one triangular removed part of the triangular removed parts, and includes an extended strip having a feed hole formed therein, and the metasurface formed on an upper surface of the upper substrate and including a plurality of unit cells. The antenna has improved performance, such as a low profile, a broadband circular polarization characteristic, a high gain characteristic, and the like.

Broadband circularly polarized antenna using metasurface

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 0.085&#x3bb;&#xd7;0.085&#x3bb;&#xd7;0.085&#x3bb;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&#x2266;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.

A small broadband monopole antenna including a shorted patch and a probe with a strip line that are electromagnetically coupled with each other. The probe with a strip line has a length of about &#x3bb;/4, where &#x3bb; is a wavelength. The strip line may be one of a spiral type, a folded type and a helix type. A resonance frequency of the antenna can be adjusted by varying the inductance and the capacitance of the resonance circuits. In addition, a double-band antenna or a single-band antenna having a broad bandwidth can be designed in accordance with application purpose of the antenna.
