  • Publication number: 20240097342
    Abstract: An antenna includes a conductive patch. The patch includes, in a plan view, a first power feed-side edge and a first non-power feed-side edge positioned on opposite sides in a first direction in one-to-one relation, and a second power feed-side edge and a second non-power feed-side edge positioned on opposite sides in a second direction intersecting the first direction in one-to-one relation. The patch includes, in the plan view, a first power feed point positioned on a side nearer to the first power feed-side edge and a second power feed point positioned on a side nearer to the second power feed-side edge. In the plan view, at least a portion of the first power feed-side edge expands outward and forms a protrusion. A width of the protrusion in the second direction gradually decreases toward a top of the protrusion. The first power feed point is positioned nearer to the top of the protrusion than a middle of a hill slope of the protrusion in the first direction.
