Invented-F plate antenna and wireless communication device |
| 摘要 |
A ground pattern 8 has a portion thereof removed in an area 13 where an inverted-F plate antenna 1 is mounted. This gives the inverted-F plate antenna 1 almost non-directional directivity patterns as distinct from those obtained with an ordinary inverted-F antenna, and helps achieve a higher degree of gain isotropy.
