Novel Compact Waveguide Dual Circular Polarizer
A novel type of dual circular polarizer for simultaneously receiving and transmitting right-hand and left-hand circularly polarized waves is developed and tested. It consists of a H-plane T junction of rectangular waveguide, one circular waveguide as an Eplane arm located on top of the junction, and two metallic pins used for matching. The theoretical analysis and design of the three-physicalpo...
متن کاملUniform and Concentric Circular Antenna Arrays Synthesis for Smart Antenna Systems Using Artificial Neural Network Algorithm
Recently, researchers were interested in neural algorithms for optimization problems for several communication systems. This paper shows a novel algorithm based on neural technique presented to enhance the performance analysis of beam-forming in smart antenna technology using N elements for Uniform Circular Array (UCA) and Concentric Circular Array (CCA) geometries. To demonstrate the effective...
متن کاملWideband Millimeter - Wave Cavity - Backed Bowtie Antenna
Although many directive antennas operating in a narrow band of millimeter (mm) waves were reported, e.g., antennas for 60GHz wireless local area network (WLAN), their wideband counterparts are still unpopular. Cavity-backed antennas (CBAs) are widely developed and reported in microwave frequency bands, but handful of literatures can be found about mm-wave CBAs in spite that their many propertie...
متن کاملThe Fresnel Rhomb as a Millimeter-wave Circular Polarizer
The present work in ̈estigates a way to produce circular polarization in the millimeter spectrum, using a Fresnel rhomb. It includes a theoretical de ̈elopment and its practical proof. Q 1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 20: 353]357, 1999.
متن کاملArtificial magnetic conductor for miniaturized antenna applications-A Review
This paper encapsulates the properties and implementation areas of Artificial Magnetic Conductor(AMC). It is characterized by having high surface impedance. The geometry of this structure is such that it does not support the propagation of surface waves and acts as a good ground plane in comparison to conventional metal conductors. Also, it reflects the waves in-phase rather than out of phase. ...
