<P>PROBLEM TO BE SOLVED: To provide a small plate-like inverse F antenna having a wide frequency bandwidth, that can be used for a frequency of about 500[MHz]. <P>SOLUTION: This plate-like inverse F antenna includes a plate-like radiation conductor 20, a plate-like short-circuiting part 30, and a plate-like feeding part 40. The longitudinal length of the short-circuit part 30 is 1/4 of the longitudinal length of the feeding part 40, the feeding part 40 is extended from a position at a distance of not more than 1/2 of the length of the radiation conductor 20 from the right end part of the radiation conductor 20 in a perpendicular direction, and a feeding point 42 is provided at a position at a distance of 1/8 of the length of the radiation conductor from the end part of the feeding part 40 including the corner end part where the short-circuit part 30 of the radiation conductor 20 is disposed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
