摘要： A base station antenna includes an internal radome and a multi-column antenna array antenna. The internal radome can be configured with a plurality of columns, each having an outwardly projecting peak segment and each neighboring column of the internal radome can be separated by a valley. Each outwardly projecting peak segment(s) is oriented to project toward a front of the base station antenna and is positioned medially aligned over a respective column of the multi-column antenna array to thereby reduce mutual coupling of respective elements and/or columns of elements and/or provide a common near field environment for each element and/or each column.

摘要： The present invention is a pole-mountable shroud assembly enclosing one or more wireless telecommunications transceivers and antennas, which extend from the pole and are rigidly attached to the pole by one or more transceiver brackets. A generally circular stationary panel is rigidly attached to the pole, and a generally annular, segmented jacked panel is attached to the pole at a vertical separation distance from the stationary panel. A panel jack, such as a screw or spring jack, connects the jacked panel to the pole so that the panel separation distance and the jacked panel circumference are adjustable. A very thin (not more than one-tenth the minimum transmission wavelength) fabric membrane shroud wraps around the circumference of the two panels, so as to form a generally cylindrical shroud enclosure which surrounds the transceivers/antennas. The panel jack is operative to tension, both vertically and radially, the fabric membrane shroud around the shroud enclosure.

摘要： An antenna assembly and an electronic device are disclosed. The antenna assembly includes a near-field-communication (NFC) integrated-circuit (IC), a conductive loop, and a radiation-field enhancer. The NFC IC includes a first differential signal port and a second differential signal port for providing a differential excitation current. The first metal stub extends from the first ground portion of the ground plane and electrically connected to the first differential signal port. The conductor is spaced apart from the ground plane, and is electrically connected to the second differential signal port and the second ground portion, respectively. The radiation-field enhancer is disposed between the conductor and the ground plane and configured to enhance a field strength of an NFC radiation-field generated by the conductor in response to the differential excitation current being transmitted.

摘要： A radar antenna includes parasitic elements for influencing the radiation characteristics of the radar antenna, the radiation characteristics of the radar antenna being dependent upon the spatial position of the parasitic elements relative to the radar antenna and phase positions (φ1, φ2, φ3) of energies radiated off the radar antenna and the parasitic elements. The radar antenna is designed using microstrip technology.
