Ultra High-Gain Displaced-Axis Metal Reflectarray Antenna for Millimeter-Wave Region

A Millimeter-Wave Wideband High-Gain Antenna Based on the Fabry-Perot Resonator Antenna Concept

A compact millimeter-wave (MMW) wideband high-gain antenna is proposed and implemented. The development is based on the design principle of wideband Fabry-Perot resonator antennas (FPRAs). The antenna consists of triple-layer dielectric slabs and a PEC ground, and it is fed by a rectangular waveguide. All slabs are used to form the superstrate that exhibits the increasing reflection phase at th...

High Gain Circular Sector Microstrip Patch Antenna for Millimeter Wave WLAN Applications

Radiation Characteristics of a circular sector micro strip antenna (CSMA) designed for the 60 GHz millimeter-wave band an application is presented in this paper. The proposed antenna consists of a circular patch with sector slot excited by micro strip feeding technique. Substrate material chosen here is the Kapton which is a polyimide used in high performance flexible printed circuit and therma...

A Millimeter-wave Slot-v Antenna

A new V-shaped slot antenna built on a dielectric substrate is presented. The antenna is a non-resonant, travelling-wave design, with a predicted impedance in the range from 50R t o €400. Calculations indicate that this antenna should have a gain of 15 dB with 3-dB beamwidths of loo in the H plane and 134' in the E plane. Pattern measurements at QOGHz support the theory. It should be possible t...

Injection Molded Millimeter-Wave Horn Array Antenna

This paper shows injection molded millimeter-wave horn array antenna for the 1-dimensional APAA(Active Phase Array Antenna). The antenna is composed of horn antennas, grooved circular waveguide polarizers, E-plane T-junctions, and E-plane bends employing dielectric waveguides. This structure makes it possible to manufacture a feed circuit and radiating elements as an integrated unit by using in...
