<p><P>PROBLEM TO BE SOLVED: To provide an adaptor for wireless communication for eliminating the generation of a null in a direction wherein the highest gain is a requirement so as to attain high sensitivity when the adaptor is inserted to an information apparatus. <P>SOLUTION: In the adaptor 1 for wireless communication having a quadrate or square board 11 and used by inserting one end of the board to the information apparatus and projecting the other end from the information apparatus, first and second monopole antennas 2a, 2b are placed to two corners of the projection region of the board 11 respectively in an attitude of being oblique to the sides of the board 11. Thus, when the adaptor 1 for wireless communication is inserted to the information apparatus, an antenna characteristic having no null in a direction opposite to the inserting direction of the board 11, that is, in a board projecting direction can be obtained. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
