Power pattern synthesis of a moving phase center time modulated antenna array using symmetrically and asymmetrically positioned time schemes

Abstract

The advantages of exploiting the harmonic patterns in a time-modulated linear array (TMLA) is presented in this paper through mathematical validation and also applied for real-world applications like beam scanning. The inherently generated harmonics or sideband radiations (SRs) in TMLAs are normally considered as a loss of power in unwanted direction. The effect of SRs at the multiple harmonic frequencies is mathematically modeled and presented in this
