Abstract
The invention consists of reduced size dipole and monopole antennas, printed on one side of a substrate with slotted loading patches at the end(s) of the antenna, and a conducting strip on the reverse side to form a folded dipole or monopole structure. The size of the structure is approximately half that of a conventional printed dipole or monopole, while maintaining or increasing the useful bandwidth. The antennas can be used in conjunction with simplified reflector and director elements to form Yagi-Uda arrays, as well as larger broadside arrays consisting of a number of Yagi-Uda arrays operated in conjunction to form a narrow fan beam. The arrays offer improved appearance due to reduced size, simpler mounting, and greater ease in alignment compared to arrays commonly in use for wireless networking.
