From:Foundations and Trends in Communications and Information Theory (Vol. 1, Issue 2) Peer-ReviewedWe consider a radio transmission whereby t antennas simultaneously transmit one signal each, and r antennas receive these signals (Fig. 2.1). Assume two-dimensional elementary constellations throughout, and the additive...

Mask-Constrained Power Synthesis of Large and Arbitrary Arrays as a Few-Samples Global Optimization.
With reference to the mask-constrained power synthesis of shaped beams through fixed-geometry antenna arrays, we elaborate a recently proposed approach and introduce an innovative effective technique. In particular, the... -
From:Progress In Electromagnetics Research M (Vol. 90) Peer-ReviewedThis paper presents the design of an 8-element linear array for Adaptive Antenna applications using the Least Mean Square (LMS) algorithm towards improving the directive gain, beam steering capabilities, half-power...

From:International Journal of Antennas and PropagationPeer-ReviewedA compact circular polarized antenna array with a convenient gain/bandwidth/dimension trade-off is proposed for applications in the C-band. The design is based on the recursive application of the sequential phase...
-
From:International Journal of Antennas and PropagationPeer-ReviewedA plasma sheath enveloping a reentry vehicle would cause the failure of on-board antennas, which is an important effect that contributes to the "blackout" problem. The method of replacing the on-board single antenna...
