An antenna system for space applications provides a membrane antenna with one or more flexible membranes. An antenna enclosure stores the membrane antenna during stowage. One or more first deployable support structures extend along a first axis from the antenna enclosure during deployment, at least a first point of the membrane antenna being operably anchored to a point on the first deployable support structures. Deployment mechanisms are operably anchored at a junction with the first deployable support structures.

At least a second point of the membrane antenna is operably anchored to a point on the second deployable support structures. Extension of the first deployable support structures and second deployable support structures unfurls the membrane antenna along both axes to overlap the junction.

A low-PIM dual pipe clamp and associated mounting bracket for securing a first pipe transverse to a second pipe at a cellular base station antenna site. The dual pipe clamp accommodates a range of pipe diameters with lower PIM generation, cost, and weight characteristics compared to conventional dual pipe clamps traditionally used at cell sites. The low-PIM dual pipe clamp minimizes the number of parts to upper and lower mounting brackets connected by linear threaded rod connectors, such as bolts, avoiding the use of U-bolts known to create PIM interference in conventional designs. The dual pipe clamp secures first and second pipes against each other in transverse orientations (e.g., horizontal and vertical), as typically utilized to mount antennas at cellular base stations. Each mounting bracket includes first and second pipe restrainers that bias the first and second pipes against each other as the threaded rod connectors are tightened.

An antenna apparatus includes a conductive radiating element, a conductive member, and a first impedance circuit. The first impedance circuit includes a first parallel resonant circuit (an LC parallel resonant circuit) and is directly connected between the radiating element and the conductive member (the conductor plate). Since the first parallel resonant circuit has high impedance in its resonant frequency band and is equivalently in an open state, one end of the radiating element is opened in the resonant frequency band. Accordingly, the radiating element defines and functions as a standing-wave antenna that contributes to electric-field radiation and a loop portion including the radiating element, the conductive member, and the first impedance circuit defines and functions as a magnetic-field radiation antenna that contributes to magnetic-field radiation.
