ABSTRACT:
In an implementation, an E-plane omni-directional antenna element includes five coplanar waveguide dipoles that are each configured to generate an e-field transmission. A center section of the antenna element couples the five coplanar waveguide dipoles to a radio frequency transmission signal such that the e-field transmission from each of the five coplanar waveguide dipoles are combined to form an E-plane omni-directional transmission pattern.
