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.
