Title:
PLANAR ANTENNA
Document Type and Number:
Japanese Patent JP2023054921
Kind Code:
A
Abstract:
To provide a planar antenna configured by aggregating a first conductor element and a second conductor element, which is provided in line symmetry with the first conductor element defined as a reference, on one side of a dielectric substrate.SOLUTION: A planar antenna 10 comprises: a linear first conductor element 210 provided on a plane 101 at one side of a dielectric substrate 100; and a second conductor element 220 which is provided in line symmetry with the first conductor element 210 defined as a reference. A first edge 221 and a second edge 222 are formed in a tapered shape which is shorter than the first conductor element 210 and tapered to be thinned toward a distal end side of the first conductor element 210. The second conductor element 220 includes a connection part 223 connected with the first edge 221 and the second edge 222 at a proximal end side of the first conductor element 210. Slits are formed between the first conductor element 210 and the side of the first edge 221, the second edge 222 and the connection part 223.SELECTED DRAWING: Figure 1
