The azimuth spacings, lengths, and surface densities of the conducting elements can be functions of meridian angle. An antenna (1130) can be mounted directly on the conducting convex surface or on a conducting or dielectric support structure mounted on the conducting convex surface.

摘要： A micropatch antenna system with simultaneous high bandwidth and low sensitivity to multipath radiation is achieved by positioning a radiating element within a cavity in a ground plane. Bandwidth and sensitivity to multipath radiation may be varied by varying the height of the radiating element above the bottom of the cavity and above the top of the ground plane. The electromagnetic and physical characteristics of the antenna system may be further controlled by introducing dielectric solids or wave-slowing structures between the bottom of the cavity and the radiating element. A dual-band micropatch antenna system with simultaneous high bandwidth and low sensitivity to multipath radiation may be similarly configured by stacking a second radiating element on top of the first radiating element.

摘要： Disclosed is a micropatch antenna comprising a radiating element and a ground plane separated by an air gap. Small size, light weight, wide bandwidth, and wide directional pattern are achieved without the introduction of a high-permittivity dielectric substrate. Capacitive elements are configured along the perimeter of at least one of the radiating element and ground plane. Capacitive elements may comprise extended continuous structures or a series of localized structures.

The inside radiator is configured as a region with a periphery, along which is a series of first protrusions separated by first grooves. The outside radiator is configured as a ring with an outer periphery and an inner periphery, along which is a series of second protrusions separated by second grooves. A set of conducting elements (208) electrically connect the series of second protrusions with the ground plane. The inside radiator and the outside radiator can be fabricated on a dielectric substrate (210) separated from the ground plane by a dielectric solid or air. The inside radiator and the outside radiator can be disposed on the same surface or on different surfaces of the dielectric substrate, with specific geometries of the first protrusions and first grooves relative to the second protrusions and second grooves.

摘要： A patch antenna system with improved multipath resistance includes a top antenna assembly and a bottom antenna assembly. Each antenna assembly includes a radiator patch and a ground plane separated by a dielectric medium. The radiator patch on the top antenna assembly is excited by an exciter and an excitation circuit. The bottom antenna assembly is electromagnetically coupled to the top antenna assembly. The resonant frequency of the bottom antenna assembly is approximately equal to the resonant frequency of the top antenna assembly. Electromagnetic fields induced in the bottom antenna assembly are in opposite phase to the electromagnetic fields excited in the top antenna assembly. Amplitudes of electromagnetic fields induced in the bottom antenna assembly are subtracted from amplitudes of electromagnetic fields excited in the top antenna assembly, and multipath signals are suppressed. Single band and dual band antenna systems suitable for global navigation satellite systems can be implemented.
