Common-Aperture Sub-6 GHz and Millimeter-Wave 5G Antenna System
IEEE Access, 2020 The realization of a common-aperture (or shared-aperture) 5G antenna system is proposed for compact and integrated wireless devices. As a combination of a dipole and tapered slots, an integrated antenna design, which operates at multi-bands, i.e.

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.
