Adaptive Correction for Radiation Patterns of Deformed Phased Array Antenna
IEEE Access, 2020 The radiation patterns of an active phased array antenna (APAA) will inevitably deteriorate in service, due to the physical deformation of the antenna surface.

IET Microwaves, Antennas & Propagation, 2023 The inconsistent polarised directions and the radiation pattern transformation of the elements need to be considered in the analysis and simulation of large circularly polarised conformal arrays. Without relying on full‐wave simulations of the full array,

Theoretical analysis and comparison of OAM waves generated by three kinds of antenna array
Digital Communications and Networks, 2021 Antenna array is one of the methods which can generate Orbital Angular Momentum (OAM) waves. However, OAM waves generated by different antenna arrays have different characteristics of Electric-field (E-field) components’ distribution and radiation ...

IOP Conference Series: Materials Science and Engineering, 2020 Abstract The radiation pattern is an important parameter of the antenna performance. This parameter needs to be measured not only accurately but also as fast as possible. For this purpose, the automatic measurement system has been developed.

PLANAR BOWTIE ANTENNA WITH A RECONFIGURABLE RADIATION PATTERN
Progress In Electromagnetics Research C, 2012 This paper presents a novel planar antenna with a reconflgurable radiation pattern. The proposed layout consists of N ‚ 2 monospaced planar bowtie antennas selected one by one by means of a pair of PIN diodes. Experimental results referring to the case of N = 2 and N = 4 are reported and discussed demonstrating the feasibility and efiectiveness of the ...
