Millimeter-Wave Metal Reflectarray Antennas with Sub-Wavelength Holes
نویسندگان
چکیده
Reflectarray antennas composed of rectangular grooves with sub-wavelength holes on a metal plate are designed for millimeter-wave regions. All depths multiple in the reflectarray elaborately manipulated high-gain reflector. A hole each groove reduces mass antenna, which rarely affects re-radiated filed from groove. In this paper, we have demonstrated light and achieved 25%-light antenna compared without holes. The operates within 15% wide-band bandwidth at 3 dB band.

Reflectarray Antennas
Printed reflectarrays combine certain advantages of reflector antennas and phased arrays. One major hurdle in the designing of reflectarrays is the compensation of phase difference between various elements. This paper presents reviews of various techniques for phase compensation, like using variable sizes of the patch, adding stubs of variable lengths and use of variable size slots on the groun...
متن کاملMembrane-supported Yagi-uda Millimeter-wave Antennas
This paper presents the design, fabrication and “on wafer” characterization of membrane-supported YagiUda CPW fed antenna structures. The antennas were designed for the 60 GHz and 77 GHz frequency operating ranges. The 60 GHz antennas were fabricated on a semi-insulating GaAs membrane using GaAs micromachining. The 77 GHz antennas were manufactured on 1.4 μm thin SiO2/Si3N4 membranes obtained b...
متن کاملPlanar Millimeter-Wave Antennas: A Comparative Study
The paper describes the design and the experimental verification of three types of wideband antennas. Attention is turned to the bow-tie antenna, the Vivaldi antenna and the spiral antenna designed for the operation at millimeter waves. Bandwidth, input impedance, gain, and directivity pattern are the investigated parameters. Antennas are compared considering computer simulations in CST Microwa...
متن کاملBlack Holes and Sub-millimeter Dimensions
Recently, a new framework for solving the hierarchy problem was proposed which does not rely on low energy supersymmetry or technicolor. The fundamental Planck mass is at a TeV and the observed weakness of gravity at long distances is due the existence of new sub-millimeter spatial dimensions. In this letter, we study how the properties of black holes are altered in these theories. Small black ...
