Abstract: Systems and methods for operating an antenna assembly. The methods comprise: receiving a first command for tuning the antenna assembly to a first frequency selected from a plurality of different frequencies to which a strip antenna of the antenna assembly is tunable; selectively connecting ground to the strip antenna at a first location along an elongated length of the strip antenna; and connecting a transceiver to the strip antenna at a second location along the elongated length of the strip antenna using a first tank circuit of a plurality of tank circuits provided with the antenna assembly. The tank circuits are respectively associated with the different frequencies to which the strip antenna is tunable. The first tank circuit is associated with the first frequency to which the strip antenna is to be tuned.

Abstract: A technique is described where the switch and/or tunable control circuit for use with an active multi-mode antenna is positioned remote from the antenna structure itself for integration into host communication systems. Electrical delay and impedance characteristics are compensated for in the design and configuration of transmission lines or parasitic elements as the active multi-mode antenna structure is positioned in optimal locations such that significant electrical delay is introduced between the RF front-end circuit and multi-mode antenna. This technique can be implemented in designs where it is convenient to locate switches in a front-end module (FEM) and the FEM is located in vicinity to the transceiver.

Abstract: A method for making an antenna comprises creating a digital antenna file defining dimensional characteristics of a radiating support structure and a ground support structure; uploading the digital antenna file to an additive-manufacturing device; manufacturing the radiating support structure and ground support structure with the additive-manufacturing device; coating one side of the radiating support structure and ground support structure with a conductive ink; attaching the radiating support structure and ground support structure together; fixing a radio frequency connector to the conductive ink on the radiating support structure and the ground support structure. The radiating support structure and the ground support structure are attached together with a dielectric adhesive.

Abstract: The present invention discloses a triple-resonant null frequency scanning antenna, which belongs to the technical fields of the Internet of Things and microwave. The triple-resonant null frequency scanning antenna comprises a circular sector magnetic dipole arranged on a medium substrate, and rectangular notches are symmetrically arranged on a sector patch of the circular sector magnetic dipole. The circular sector magnetic dipole is fixed on the medium substrate by a second shorting pin and third shorting pins, an flared angle of the circular sector magnetic dipole is a first central angle, and two third shorting pins are present and are symmetrically arranged on both sides of the angular bisector of the first central angle.

Abstract: Various cellular tower plate connection systems are detailed herein. Such systems can include an antenna plate assembly. This assembly can include an antenna plate and antenna port connectors attached to a first side of the antenna plate. Cable connectors may be present that are attached to a second side of the antenna plate opposite the first side of the antenna plate. The assembly can include a first attachment mechanism that secures antenna port connectors to antenna ports of an antenna system. The antenna port connectors may be arranged on the first side of the antenna plate such that the antenna port connectors mate with the antenna ports of the antenna system in a single possible orientation.

Abstract: A compact munition antenna system that includes a curvilinear transmit antenna on a top and bottom of a ring-shaped substrate, and a curvilinear receive antenna on the top and bottom of the substrate. The transmit antenna and receive antenna are positioned opposite one another on the substrate, and are separated by a pair of isolation barriers to reduce coupling of the two antennas. The munition antenna system may be mounted on a metal cylindrical portion of a guidance system in a nose section of the munition, using a vertical convex surface of the cylindrical portion and a horizontal surface of the munition as a reflector for improving antenna performance.
