Reconfigurable Slot-Array Antenna With RF-MEMS [PDF]
IEEE Antennas and Wireless Propagation Letters, 2011 Cylindrical near-field measurement systems are being widely demanded, especially for imaging applications at millimeter-wave frequencies. One of their most important drawbacks is the long time required to perform a full measurement of an antenna. To avoid multiple receivers, the probe is mechanically moved to the points where the field must be measured.

Design and research of single‐sided slotted waveguide antenna with a large beam declination
IET Microwaves, Antennas & Propagation, 2021 The slot of the conventional longitudinal slot antenna is alternately opened on both sides of the broadside. A novel single‐sided slot array with a large‐declination (biased towards the load) is proposed, in which the slots are only biased to the same ...

Millimeter Wave Substrate Integrated Waveguide Antennas: Design and Fabrication Analysis [PDF]
, 2009 The paper presents a new concept in antenna design, whereby a photo-imageable thick-film process is used to integrate a waveguide antenna within a multilayer structure. This has yielded a very compact, high performance antenna working at high millimeter-

IEEE Open Journal of Antennas and Propagation, 2022 Modern antenna arrays desire antenna apertures which can support a wide frequency range and reconfigurable polarization states. It is challenging to realize such antenna apertures with high isolation among different antenna elements when they are closely
