The reason for the presence of unwanted sidelobes in multifeed single-beam reflectarrays and power combiners is shown to be a grating lobe phenomenon due to “amplitude clustering” of the scattered field over the reflectarray aperture. A means of

A new cell element is introduced for broadband reflectarray applications. The presented unit cell exhibits linear phase response which makes it a suitable candidate for broadband X-Ku band applications. This cell element consists of three concentric

Orthogonally-polarized dual-band MEMS-tunable double-slotted unit cell for reflectarray applications
Publikováno v:
Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation.
This paper presents a single-layer MEMS-reconfigurable reflective unit cell that supports two bands (12 and 14 GHz) at two orthogonal polarizations. A pair of MEMS varactors is used for continuous and independent tuning of each band. The dynamic phas

Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation.
This paper presents a single-layer single-sided dual-band MEMS reconfigurable reflectarray unit cell operating at 12 and 14 GHz. Each operating bands can continuously and independently be tuned using a pair of MEMS varactors at vertical and horizonta
