A planar antenna clamp system comprising: a base; a connector mounted to the base; a clamp arm mounted to the base such that, when in an open configuration, an air gap exists between the top surface of the base and the bottom surface of the clamp arm's distal end, and wherein the clamp arm and the base are oriented with respect to one another such that conductors of a planar antenna may be positioned in the air gap when in the open configuration; a matching circuit disposed on the top surface of the base and electrically connected to the connector; and a clamp configured to compress the conductors of the planar antenna between the top surface of the base and the bottom surface of the clamp arm such that the conductors of the planar antenna are operatively coupled with the matching circuit, when in a closed configuration.

Planar antenna clamp system

An antenna comprising first and second antenna elements, a center conductor, and a dielectric. The first antenna element is configured to be electrically connected to an outer conductor of a coaxial cable. The center conductor is electrically connected to the second antenna element and configured to be electrically connected to an inner conductor of the coaxial cable. The dielectric is disposed around the center conductor so as to separate the center conductor from the first antenna element. The first antenna element is shaped to gradually surround the dielectric and the center conductor over a length of the first antenna element so as to form a balun, integrated into the first antenna element, that is configured to gradually transform an unbalanced signal in the coaxial cable to a balanced signal that is characteristic of a two-conductor transmission line.

Antenna with integrated balun

A dual-polarized tapered slot antenna (TSA) comprising: a dielectric bracket; a first pair of conductive blades mounted to the dielectric bracket so as to define a first tapered slot between edges of the conductive blades of the first pair thereby forming a horizontally-polarized TSA; a second pair of conductive blades mounted in the dielectric bracket orthogonal to the first pair so as to define a second tapered slot between edges of the conductive blades of the second pair thereby forming a vertically-polarized TSA; and wherein at least part of each of the slot-defining edges of the conductive blades has a thickness that is non-tapered and stepwise-reduced from the thickness of a remainder of the corresponding blade.
