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.

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 ...

Optimising radio coverage for wireless media servers [PDF]
, 2010 A three element patch antenna array is designed for a 2×3 802.11n wireless home media server application for highdefinition video streaming at 2.4GHz. An efficiency comparison shows that the use of the RT/Duroid substrate results in a 3dB improvement in ...

Radiation Pattern Reconfigurable FM Antenna
Journal of Physics: Conference Series, 2019 Abstract In this work, a radiation pattern reconfigurable antenna design using compact printed spiral monopoles that operates at 102 MHz is reported. The proposed antenna changes its radiation behaviour that responds towards a desired direction with the use of RF switches.

Compact loaded PIFA for multifrequency applications [PDF]
, 2010 A new multifrequency microstrip patch antenna is presented. The antenna can be considered a PIFA since it has a metallic wall on one of its sides. The different bands of operation are independent of each other, and different radiation patterns for each ...

A reconfigurable radiation pattern annular slot antenna
2016 Loughborough Antennas & Propagation Conference (LAPC), 2016 This paper contemplate a theoretical analysis of a pattern reconfigurable antenna using annular slot antenna operating in low frequency. A shorting pin is inserted to allow the annular slot antenna to have an omni-directional radiation pattern like a monopole antenna.
