Abstract

A wireless communication device includes at least one antenna configured to transmit or receive a signal, and a frequency selection surface arranged adjacent to the at least one antenna and configured to diffract the signal generated from the at least one antenna, wherein the frequency selection surface includes a transparent substrate on which a plurality of unit cells are defined, and a plurality of conductive patterns arranged in the plurality of unit cells, respectively.

First claim

What is claimed is:

1 . A portable terminal comprising:
at least one antenna transmitting a first radio frequency (RF) signal; a display indicating a processing status of the portable terminal; a transparent substrate covering the display and the at least one antenna; and a plurality of conductive patterns arranged on the transparent substrate, wherein the plurality of conductive patterns are configured to receive the first RF signal to generate a second RF signal.

2 . The portable terminal of claim 1 , wherein a width of each of the plurality of conductive patterns is equal to or less than 1/20 of a wavelength of the first RF signal.

3 . The portable terminal of claim 1 , wherein the plurality of conductive patterns diffract the first RF signal such that the first RF signal avoids an obstacle adjacent to the portable terminal.

4 . The portable terminal of claim 1 , wherein each of the plurality of conductive patterns resonates with the first RF signal.

5 . The portable terminal of claim 1 , wherein the at least one antenna is located in a central portion of the transparent substrate.

6 . The portable terminal of claim 1 , wherein the at least one antenna is located at an edge of the transparent substrate.

7 . The portable terminal of claim 1 , wherein the at least one antenna comprises a plurality of antennas.

8 . A communication device comprising:
an antenna configured to generate a radio frequency (RF) signal; and a frequency selection surface configured to diffract a signal generated from the antenna around a surrounding obstacle.

9 . The communication device of claim 8 , wherein the frequency selection surface comprises:
a glass substrate; and conductive patterns arranged in a matrix on the glass substrate.

10 . The communication device of claim 9 , wherein each of the conductive patterns comprises:
an adhesive layer for adhering to the glass substrate; and a conductive layer arranged on the adhesive layer.
