A dual feed slot antenna can include a ground plane formed with an aperture, and first feed and second feeds extending into the aperture. The first feed and second feed can extend into the aperture so that the first feed and second feed are coincident and out of phase with other. The first feed and said second feed can define a U-shaped stub, with a respective stub length, a stub width, a crossbar and a pair of stub tines defining a stub separation extending from the crossbar. The first feed and second feed can extend into the aperture so that each of the stub tines from a first feed are coincident the stub tines from the second feed. With this configuration, and with further selection of the said respective stub lengths, stub widths and stub separations, a symmetric omnidirectional radiation can be established for the antenna.
