A controllable dual input/output port power divider coupled with a controllable phase shifter feed a dual ported dual polarized microstrip antenna structure. By controlling the power divider and phase shifter, arbitrary orthogonal polarization (e. g. , linear, circular or elliptical) radiated r. f. fields are obtained. Virtually the entire structure comprising the dual port power divider, phase shifter and microstrip radiator may be formed of shaped photo-chemically etched microstrip conductors disposed a very short distance (e. g. , less than one-tenth wavelength) above a conductive reference surface.

A relatively broadband printed circuit antenna structure includes a dielectric sheet having printed circuit-like conductive structures printed on both sides in predetermined registration with one another. A traditional non-radiating microstrip transmission line structure extends from a common r. f. feedpoint to at least one terminal end portion. However, apertures disposed within the underlying (or overlying) conductive reference surface of the double-cladded printed circuit board in the vicinity of each terminal end cause substantial r. f. radiation to occur over a relatively broader bandwidth than with a more traditional microstrip antenna radiator structure. In one embodiment, the aperture in the microstrip ground plane itself becomes a radiating aperture due to the transmission line currents flowing within the ground plane. In other embodiments, the terminal end portion of the microstrip transmission line becomes a monopole radiator when it is encompassed by an aperture or opening in the pattern of the printed ground plane. A conductive reflector surface may also be disposed about one-fourth wavelength behind the printed ground plane--unless radiation directed away from either side of the antenna structure is desired.

A small size, flat panel, 1/6. sup. th wavelength antenna is provided. A flat copper-clad dielectric substrate is processed on a first flat side to produce a copper triangular or pseudo triangular-shaped radiating element having a linear copper feed line that extends from the triangle apex. The substrate is also processed on its opposite flat side to produce a rectangular-shaped first copper ground plane element that underlies at least a portion of the copper feed line, but does not underlie the copper radiating element. The first side of the substrate may also be processed to produce a second copper ground plane element that is out of physical engagement with both the copper feed line and the copper radiation element. Aligned through holes are formed in the first ground plane element and the substrate. The metal sheath of a coaxial cable connects to the copper ground plane member(s), and the cable center conductor penetrates the aligned through holes and connects to the copper feed line.

A monolithic microwave integrated circuit including an integral array antenna. The system includes radiating elements, feed network, phasing network, active and/or passive semiconductor devices, digital logic interface circuits and a microcomputer controller simultaneously incorporated on a single semi-insulating GaAs substrate by means of a controlled fabrication process sequence. The resulting integrated circuit structure built upon a semi-insulating GaAs substrate provides a unique monolithic structure capable not only of phase-shifting, amplifying or otherwise controlling and conducting r. f. electrical signals but also capable of directly radiating/receiving r. f. electromagnetic emanations propagated to/from the integral antenna elements of the monolithic structure.

A Radio Frequency (RF) microstrip antenna employs a planar or curved radiator element that is mounted or supported in spaced relation to a planar or curved ground plane element. A RF feed is attached near one edge of the radiator element for receiving and/or transmitting RF signals in a lobe that is substantially perpendicular to the ground plane element. The radiator element and the ground plane element are maintained in a converging or tilted physical relationship. When a coaxial cable is employed as the antenna feed, the cable's outer insulation is secured to the ground plane element, the cable's center conductor extends away from the ground plane element to provide a signal feed to the radiator element and to provide physical support for one edge of the radiator element, and two insulator posts extend away from the ground plane element to provide support for the opposite edge of the radiator element.

A dual slot antenna assembly is disclosed herein and generally includes a pair of concentrically positioned and radially spaced cylindrical conductors defining a pair of circumferential slots which are longitudinally spaced one-half wavelength apart at the anticipated operating frequency of the antenna device. An electrical signal feed assembly is connected with the conductors for exciting the slots so as to provide overlapping radiation patterns emanating in the same direction.

A resonant circularly or elliptically polarized microstrip radiator wherein the size of the radiator is reduced in the resonant or non-resonant dimensions, or both, without reducing the effective resonant dimension or substantially lowering the efficiency of the radiator. Reduction of the resonant dimension is provided by folding the resonant cavity, while reduction of the non-resonant dimension is facilitated by utilization of a low density, low loss dielectric, such that the loss resistance of the element is appreciable with respect to the radiation resistance of the element. The preferred embodiment comprises interdigitated antenna structures.
