| 摘要 |
An apparatus is disclosed for a communication device ( 100 ) with a wideband antenna ( 102 ) supporting at least two common and one differential resonant modes. An apparatus that incorporates teachings of the present invention may include, for example, the communication device having an antenna ( 102 ) that includes a ground structure ( 202 ), a first elongated conductor ( 204 ) spaced from the ground structure, a second elongated conductor ( 206 ) separated from the first elongated conductor, third and fourth conductors ( 212 ) each coupled to the first and second elongated conductors forming a gap ( 205 ), a ground conductor ( 208 ) coupling the ground structure to one among the first and second elongated conductors, and a signal feed conductor ( 210 ) coupling to one among the first and second elongated conductors spaced from the ground conductor. Additional embodiments are disclosed. A -10 dB bandwidth of at least 0.5 can be realized using electrical non-congruence.
