Abstract:
1. An antenna comprising first and second multi-frequency antennas, each comprising: a first antenna with multiple resonant frequencies, comprising a first input/output terminal, a first antenna conductor, a series circuit of a first inductor and a first capacitor connecting the first input/output terminal and the first antenna conductor, and a second inductor one end of which is connected to the first antenna conductor; a second antenna with multiple resonant frequencies, comprising a second input/output terminal, a second antenna conductor, a series circuit of a third inductor and a second capacitor connecting the second input/output terminal and the second antenna conductor, and a fourth inductor one end of which is connected to the second antenna conductor and the other end of which is connected to the other end of the second inductor; and wherein the first antenna and the second antenna are positioned substantially mirror-image symmetrically; wherein the first multi-frequency antenna and the second multi-frequency antenna are positioned so as to intersect substantially orthogonally at a center point, and the other end of the fourth inductor of the first multi-frequency antenna is further connected to the other end of the fourth inductor of the second multi-frequency antenna.
