This letter presents a novel concept of beam-steerable transponder based on antenna array and phased modulators. The steerability the beam is achieved by optimally delaying modulated reflected signal at each element (i.e., changing phase in frequency domain) with load modulation technique. In this manner, backscattered power can be maximized one particular direction. approach makes to collect a...

A fully printable and conformal antenna array on a flexible substrate with a new LeftHanded Transmission Line (LHTL) phase shifter based on a tunable Barium Strontium Titanate (BST)/polymer composite is proposed and computationally studied for radiation pattern correction and beam steering applications. First, the subject 1× 4 rectangular patch antenna array is configured as a curved conformal ...

in this article, the linear array (with 20 elements in the horizontal orientation) of microstrip antenna is examined with horizontal polarization. the set includes three microstrip substrates. there is a power network in two lower substrates and microstrip patches in the upper substrate. excitation of patches has been done as coupled through the power network in two lower substrates. using the ...
