Abstract
The object of the present invention is to provide an antenna pair that has the advantages of easy installation and improved gain. According to the present invention, the antenna pair consists of two slot antennas formed on a metallic strip and sharing a common portion of the strip as the grounding unit. The grounding portions of the antennas join together to become the grounding unit so as to increase the effective antenna aperture for both of the antennas and to raise their gains. As the antennas are combined into one, it is more manageable and handy for installation. The grounding unit can be further extended to allow greater improvement. The strip on which the slot antennas are formed is curved to have the antennas orthogonal to each other. The orthogonality brings about the space diversity effect and prevents the occurrence of any null in the radiation pattern of the antennas.
