Patent attributes
A dipole antenna comprising a base; first and second pairs of dipoles positioned in front of the base and arranged around a central region; a first feed line which extends from the base towards the dipoles and splits at a first junction positioned in front of the base into a first pair of feed probes each of which is coupled to a respective one of the first pair of dipoles; and a second feed line which extends from the base towards the dipoles and splits at a second junction positioned in front of the base into a second pair of feed probes each of which is coupled to a respective one of the second pair of dipoles. The feed probes are spaced from the dipoles so as to field-couple with the dipoles. In one embodiment, the first pair of feed probes is positioned on a first side of the dipoles and the second pair of feed probes is positioned on a second side of the dipoles opposite to the first side. In another embodiment, the dipoles are printed on a PCB.
