1. A modular wideband antenna comprising:
a ground plane;
a first antenna element and a second antenna element disposed on a first surface of a substrate, the first antenna element is electrically coupled to the ground plane, a first segment of the first antenna element extends parallel to a first segment of the second antenna element along the substrate and a second segment of the first antenna element diverges from a second segment of the second antenna element along the substrate, the second antenna element is coupled to a signal feed, the first antenna element has a first horizontal stub element electrically coupled to a second section of the first antenna element, and the second antenna element has a second horizontal stub element electrically coupled to the second section of the second antenna element; and
a first wall and a second wall disposed on a second surface of the substrate, the first wall having a first end electrically coupled to the ground plane, the second wall having a first end electrically coupled to the ground plane, the first wall being capacitively coupled to the first antenna element and the second wall being electrically coupled to the second antenna element.
