Abstract:
1. A chip antenna for terrestrial DMB, comprising: a dielectric block with a plurality of dielectrics having an XY plane laminated in the direction of the Z-axis therein; a main antenna device formed with conductive patterns in the dielectric block, such that a plurality of unit lamination structures of the conductive patterns having a meander line structure in the direction of the Z-axis in an XZ plane are arranged in the direction of the Y axis, adjacent unit lamination structures are connected to each other, forming a lamination structure having the meander line structure in the direction of the Y-axis, and such that the plurality of lamination structures are arranged in the direction of the X-axis and adjacent lamination structures are connected to each other in the direction of the X-axis to have the meander line structure; and a T-shaped assistant antenna device formed at an upper or lower dielectric layer in the main antenna device while being connected to one end of the main antenna device through a conductive via-hole so that the assistant antenna device dissipates current distribution of the main antenna device, thereby widening bandwidth.
