The origin of conformal arrays can be traced at least back to the 1930s when a system of dipole elements arranged on a circle, thus forming a circular array, was analyzed by Chireix [1936]. Later, in the 1950s, several publications on the subject were presented; see, for example, [Knudsen 195[r]

The objective of this special issue is to address these crit-ical aspects and present the most recent developments in the areas of antenna array design, implementation, measure-ments, an[r]

This paper presents a microstrip antenna design which it''s radiating element is circular and applied to 5G systems. The model and parameters of the antenna were simulated and analyzed by High-Frequency Structure Simulator (HFSS) computer code on FR4-epoxy laminate microwave.

Experiment shows that whenever the dimensions of the aperture are large compared with the Ivavelcngth, the diffraction effects are small and the major portion of the field pattern is concentrated in the region covered by the rays from the aperturẹ On the basis of this fact a common high- frequency a[r]

The LNAs used in M/A-COM’s active antennas are high performance GaAs MMICs in low cost SOIC 8-lead surface mount plastic packages. These LNAs employ monolithic 3 stage self-bias designs and a simple external matching network (PC board), to obtain a minimum noise figure. The LNA is ideally suit[r]
