Systems and methods for providing a broadband antenna are disclosed. The antenna can include a current sheet array having a plurality of antenna elements. Each antenna element includes dipole arms. The dipole arms can be configured as first and second dipole arm pairs for transmitting or receiving signals of different polarizations. A resistive-capacitive (RC) loading structure is provided for each antenna element, in a layer between the antenna elements and a surface of an antenna substrate. Each RC loading structure includes a set of conductive surfaces and a set of resistive surfaces. A dielectric layer separates the RC loading structure elements from the dipole arms.

Ultra-broadband current sheet array

Systems and methods for providing an electrically small antenna are provided. The antenna can include an arm or a pair of arms disposed on a surface of a substrate. The substrate and the arm or arms are generally disposed in an aperture or volume formed in a housing. A capacitive gap is provided between the arm and the housing, or between the arms. Where the antenna includes a pair of arms, each arm generally includes a main portion disposed on the first surface of the substrate and a perpendicular portion that extends from the first surface of a substrate towards a ground plane on a second surface of the substrate. The perpendicular portions of the arms face one another. In addition, the main portions of the arms can be tapered in plan view. A ground plane can be provided on the second surface side of the substrate.

Electrically small wideband resonant loop antenna systems and methods

Systems and methods for providing a high gain antenna are disclosed. The antenna can include an array of active antenna elements disposed on a first side of a first circuit board. The active antenna elements are grouped into a number of super elements. Each super element occupies at least a portion of an outside edge of an area containing the active antenna elements. Passive antenna elements can be disposed so as to surround the area containing the active antenna elements. Passive circuit components can be disposed on a second side or on an intermediate layer of the first circuit board. Active circuit components can be disposed on a second circuit board. The active components can be supplied with power and control signals. The first and second circuit boards can be held together by a housing. The antenna can be configured as conformal array antennas.

Conformal antenna system

Systems and methods for providing a broadband antenna are provided. The antenna can include a current sheet array having a plurality of elements. Each of the elements includes dipole arms. The dipole arms can be configured as first and second dipole arm pairs for transmitting or receiving signals of different polarizations. Capacitive structures are provided between adjacent branch portions of the dipole arms. The capacitive structures extend from a first side of a substrate on which the dipole arms are located towards a second side of the substrate.

Current sheet array antenna

Systems and methods for providing a broadband antenna are described. The systems and methods involved providing a current sheet array. The current sheet array comprises a plurality of unit cells coupled together. Each unit cell comprises a slot and a stripline feed. The stripline feed couples to a dipole array through the slot. An electric field in the slot of a first unit cell is perpendicular to one or more of the stripline feed of the first unit cell and one or more dipoles of the first unit cell.
