Abstract
Provided is a planar antenna including an antenna array in which a plurality of patch antennas are disposed in a two-dimensional array; a substrate on which a phase shifter layer including a phase shifter associated with each of the plurality of patch antennas and wiring used for controlling the phase shifter is formed; a signal line through which a communication signal propagates; and a ground layer disposed between the phase shifter layer and the signal line, and having a slot formed at least between the signal line and the phase shifter.

A planar antenna comprising:
- an antenna array in which a plurality of patch antennas are disposed in a two-dimensional array;
- a substrate on which a phase shifter layer including a phase shifter associated with each of the plurality of patch antennas and wiring used for controlling the phase shifter is formed;
- a signal line through which a communication signal propagates;
- and
- a single ground layer disposed between the phase shifter layer and the signal line, and having a slot formed at least between the signal line and the phase shifter, wherein
- the wiring includes selection lines and data lines,
- the signal line intersects with the selection lines and the data lines,
- the single ground layer is positioned between both the phase shifter and the wiring on one side and the signal line on an opposite side, and
- the single ground layer prevents interference at locations where the signal line intersects with the selection lines and the data lines.
