Low-Cost S-Band Reconfigurable Monopole/Patch Antenna for CubeSats
IEEE Open Journal of Antennas and Propagation, 2020 The development of reconfigurable antennas compatible with a CubeSat form factor can aid several space missions. Often, satellite missions require multiple wireless links with the same radio, but the design of such antennas is challenging due to the ...

A Deployable Volume-Efficient Miura-Ori Reflectarray Antenna for Small Satellite Applications
IEEE Access, 2023 Traditional high-gain antennas, like parabolic reflectors and phased arrays, are challenging to implement on small satellites (SmallSats) due to their reduced volume when stowed for launch.

Directive properties of radiating source systems in massive electromagnetism
Results in Physics, 2022 We investigate the problem of electromagnetic radiation in massive electromagnetism with focus on the directive radiation characteristics of Proca antennas (sources embedded into Proca metamaterial domains.) It is theoretically demonstrated that the ...

Modelling of Path Arrival Rate for In-Room Radio Channels with Directive Antennas [PDF]
, 2017 We analyze the path arrival rate for an inroom radio channel with directive antennas. The impulse response of this channel exhibits a transition from early separate components followed by a diffuse reverberation tail.

Super Directional Antenna—3D Phased Array Antenna Based on Directional Elements
Electronics, 2022 This paper describes an antenna design approach for achieving super directivity in an AESA (Active Electronic Scanned Array) radar using an unconventional 3D phased array (PA) antenna concept based on directional Yagi–Uda elements. The proposed scheme is shown to have a wider scanning feature, with higher directivity in comparison to the same geometry ...

Novel antenna configurations for wireless broadband vehicular communications [PDF]
, 2010 In this paper, mobile WiMAX trials are analysed to investigate the vehicular down-link performance for a number of on-car antenna configurations. The directionality and optimum polarization of the vehicular antennas are shown to improve both the range ...
