摘要： A system includes a support device and an elongated spiral antenna coupled to the support device. The elongated spiral antenna has a contracted portion and an expanded portion. The expanded portion provides beam steering and directivity. The system also includes a feed line coupled to the elongated spiral antenna. A method for forming the elongated spiral antenna uses a predetermined formula to form arms of the elongated spiral antenna. The arms can be formed by printing the arms on a printed circuit board.

摘要： An antenna includes a magnetic interface generator that generates a magnetic interface at a center frequency f0. The magnetic interface generator is a passive array of spirals that are deposited on one layer of a multi-layer substrate. The magnetic interface is generated in a plane at a distance Z above the surface of the substrate layer that it is printed on, where the antenna in printed on a second layer of the multi-layer substrate. The distance Z where the magnetic interface is created is determined by the cell size of the spiral array, where the cell size is based on the spiral arm length and the spacing S between the spirals. The center frequency of the magnetic interface is determined by the average track length DAV of the spirals in the spiral array. The spacing S of the spiral array is chosen to project the magnetic interface to the second layer in the multi-layer substrate so as to improve performance of the antenna that printed on the second layer. The magnetic interface can be used to increase the gain, matching, and bandwidth of a microstrip patch antenna, or other type of antenna.

摘要： A magnetic interface generator generates a magnetic interface at a center frequency f0. The magnetic interface generator is a passive array of spirals that are deposited on a substrate surface. The magnetic interface is generated in a plane at a distance Z above the surface of the substrate. The distance Z where the magnetic interface is created is determined by the cell size of the spiral array, where the cell size is based on the spiral arm length and the spacing S between the spirals. The center frequency of the magnetic interface is determined by the average track length DAV of the spirals in the spiral array. In embodiments, the spiral array is one sub-layer in a multi-layer substrate. The spacing S of the spiral array is chosen to project the magnetic interface to another layer in the multi-layer substrate so as to improve performance of a circuit in the plane of the magnetic interface. For example, the magnetic interface can be used to increase the inductance of a printed inductor circuit, and to increase the gain and match of a microstrip patch antenna. Furthermore, the magnetic interface reduces the traverse electric (TE) and transverse magnetic (TM) surface waves in the plane of the magnetic interface, which reduces unwanted coupling between transmission lines.
