Ultrawideband Antenna Arrays and Directional Propagation Channels

The large spectral occupancy of ultrawideband (UWB) wireless signals significantly complicates the design of multi-antenna arrays and the characterization of propagation channels determining the performance of such arrays. This survey paper develops generic techniques for double-directional UWB channel characterization, and surveys methods for the extraction of the parameters of multipath compo...

design of a novel directional microstrip-fed super-wideband antenna

in this paper, a novel directional super wide band micro strip antenna based on a simple and new geometry has been proposed. the antenna exhibits the widest bandwidth ever reported to the authors’ knowledge from 50 ghz to 200 ghz. its radiation pattern is approximately steady in the frequency ranges of 50 ghz to 200 ghz. the antenna consists of a club-like radiating patch, a combination of thre...

Omni Antenna vs. Directional Antenna

An antenna gives the wireless system three fundamental properties: gain, direction and polarization. Gain is a measure of increase in power. Gain is the amount of increase in energy that an antenna adds to a radio frequency (RF) signal. Direction is the shape of the transmission pattern. As the gain of a directional antenna increases, the angle of radiation usually decreases. This provides a gr...

A Hybrid Optimization for Pattern Synthesis of Large Antenna Arrays

The pattern synthesis for large antenna arrays has drawn significant attention because of its wide applications. This paper introduces a hybrid approach for the fast pencil beam pattern synthesis of the large non-uniform linear or planar array, which can significantly reduce the computational cost, the number of antenna in the array, the minimum sidelobe level and the null control. The proposed...

Synthesis of Antenna Arrays of Maximum Directivity for a Specified Sidelobe Level

Linear and planar antenna arrays are synthesized to have maximum directivity for a specified sidelobe level. The directivity is maximized subject to a given SLL. The beamwidth and the zeros of array factor are studied as well as the directivity. Maximum directivity-arrays are compared through some examples with super-directive, uniform, Dolph-Chebyshev and Riblet-Chebychev arrays to find a comp...
