E-plane omni-directional antenna is described. In an embodiment, a transmission signal connection system includes a center conductive rod to communicate a radio frequency transmission signal, and includes one or more outer conductive rods that each provide a grounded return for the radio frequency transmission signal and shield the center conductive rod. The center conductive rod and the one or more outer conductive rods also couple a first antenna element to at least a second antenna element, and the center conductive rod couples the first antenna element and the at least second antenna element to the radio frequency transmission signal. Each antenna element includes coplanar waveguide dipoles that generate an e-field transmission which are combined to form an E-plane omni-directional transmission pattern.
