PROBLEM TO BE SOLVED: To provide a chip antenna which can improve effective antenna gain and improve circuit quality by enabling transmission/reception of plural kinds of linearly polarized wave.;SOLUTION: A chip antenna 1 is formed in a rectangular parallelepiped dielectric block 4. A first linear radiating element 6 is formed on one side (the upper surface) of the dielectric block 4. A second radiating element 5 is bent and connected to one end G of the radiating element 6 and on one side of the dielectric block 4. The dielectric block 4 has a ground conductor 2 on the other side (the bottom surface). A third radiating element 8 connects the ground conductor 2 and the other end C of the radiating element 6 approximately vertically to the ground conductor 2. The other side of the dielectric block 4 has a first electrode 3 for insulation from the ground conductor 2. A feeder line is connected between the electrode 3 and a point P of the radiating element 6. Elements 5 and 6 transmit/receive horizontally polarized waves, while the element 8 and an element 7 of the feeder line transmit/receive vertically polarized waves.;COPYRIGHT: (C)2002,JPO
