Phase modulation (PM) techniques based on time modulated arrays (TMAs) are usually
used to generate a steerable beam at the carrier frequency. However, the overall efficiency …

An improved modulation module for beam steering in time-modulated array (TMA) is
presented and investigated. The general improved module deploys parallel submodules …

Traditional time-modulated antenna arrays (TMAs) usually introduce sideband radiations at
a multiple of discrete harmonic frequencies. To improve radiation efficiency of TMAs, various …

Because of the multiplication of antennas, harmonic beamforming based on the time-
modulated planar array (TMPA) requires a much longer modulation period than the time …

We present a single sideband time-modulated multibeam phased array governed by
periodic Nyquist pulsed signals. A Nyquist pulse is a physically realizable approach to the …

Time-modulated array (TMA) naturally generates a large number of sidebands to achieve
multibeam radiation. Conventional multibeam TMAs using rectangular modulation signals …

Conventional time-modulated arrays are based on the application of variable-width
periodical rectangular pulses (easily implemented with radio frequency switches) to the …

In this paper, a novel module named time-modulated amplitude-phase weighting with
multiple branches (TMAPW-MB) is proposed to realize harmonic beamforming. The …

Time-modulated arrays (TMAs) are able to improve the side-lobe level of the radiation
pattern at the fundamental mode but cannot steer the beam at such a mode towards a given …

In this paper, a novel technique for electronic beam steering in time modulated linear array
(TMLA) is proposed. The beam steering technique is realized at the first sideband by …
