Abstract:

The concept so called "time modulated antenna array" is a type of antenna array whose elements are switched according to a periodic switching function. Due to periodic switching, naturally, harmonic radiations (i.e. sidebands) are being created and most studies in the literature focus on suppressing these unwanted sidebands. In the light of development on time modulated antenna array concept it has been seen that instead of suppressing sidebands, they may be used for different purposes such as secure communication and direction finding applications. In this thesis, it has been shown that if a sideband has enough power, it may be used as an additional receiver whose frequency is different from central frequency of the array. In order to present better understanding on the study, a simulation showing reception and demodulation of two different message signals modulated respectively with amplitude and frequency modulation has been realized using time modulated linear array and its successful results have been obtained.
