1. An antenna comprising:
a planar dielectric substrate;
a primary conductive area on a first surface of the planar dielectric substrate, wherein the primary conductive area has a shape defining: a first region of the first surface bounded by at least a portion of the primary conductive area, and a second region comprising a remaining portion of the first surface;
a first secondary conductive area on the first surface, wherein the first secondary conductive area lies in the first region of the first surface;
a second secondary conductive area provided on the first surface, wherein the second secondary conductive area lies in the second region;
a ground plane on a second surface on other side of the planar dielectric substrate; and
a primary stem connected to the primary conductive area;
wherein the first secondary conductive area comprises a secondary stem.
