Disclosed is an antenna phase shifter that comprises an outer conductive trace, an inner conductive trace, a wiper arm having a pivot point, and a capacitive coupler that capacitively couples an input port to the wiper arm conductive trace and capacitively couples the input port to a phase reference port. The capacitive coupler provided DC blocking between the input port and the phase reference port, and the input port may be coupled to a Bias-T such that the DC component present at the input port may be coupled to the Bias-T to drive the phase shifter wiper arm motor. In addition, the capacitive coupler provided constant capacitance while the wiper arm rotates.

Disclosed is a telecommunications antenna having a plurality of cloaked low band (LB) and high band (HB) dipoles. The LB and HB dipoles provide cloaking by breaking the dipoles into dipole segments, and providing conductive cloaking elements over the gaps between dipole segments to form a plurality of capacitors along the dipole. The capacitors along the LB dipoles provide a low impedance to LB RF signals and a high impedance to HB signals. The capacitors formed on the HB dipoles provide a low impedance to RF signals and high impedance to harmonics of the LB RF signals. This cross-cloaking of dipoles enables more dense arrangements of LB and HB dipoles on an antenna array face, providing opportunities to arrange, for example, the LB dipoles with an array factor that results in an advantageous fast roll off gain pattern.

Optically transparent, highly conductive conductor materials are provided, which in certain variations may also be flexible. Methods of making transparent conductive conductors, such as electrodes, are also provided. Such a method may include creating a groove pattern on a substrate that defines a two-dimensional array. Then an electrically conductive material may be selectively applied within the groove pattern of the substrate so as to create a transparent conductor (e.g., a transparent conductive electrode (TCE)). The transparent conductor has a sheet resistance of ≤about 5 Ohms/Square and a transmissivity of ≥about 50% for a predetermined range of target wavelengths of electromagnetic energy. Such methods may form linear micromesh conductive arrays and tortuous micromesh conductive arrays that can be used in a variety of optoelectronic applications, including as optically transparent, flexible and mechanically reconfigurable zeroth-order resonant (ZOR) antennas.

A unit cell for an antenna comprises a conductive ground plane, a low-band radiator, a pair of high-band radiators, and a conductive partition disposed along an edge intersecting a pitch axis of the conductive ground plane. The low-band radiator comprises a pair of orthogonally coupled dipoles each having a vertical stem portion and an arm portion. Each arm disposed in a plane orthogonal to the conductive ground plane. The arm portions, collectively and on-edge, produce an L-shaped radiator parallel to the conductive ground plane. Each of the high band radiators comprises a pair of cruciform radiators, each cruciform electrically connected to, spaced-apart from, and parallel to the conductive ground plane. The conductive partition isolates at least a portion of the RF energy transmitted by the low and high-band radiators.
