Dual resonators in a one-dimensional (1D) electromagnetic band gap (EBG) application into array antenna is investigated as a mean to enhance the directivity and the radiation bandwidth. The directivity increases significantly with a number of patches using 1D-EBG, is obtained 24.44dB for an array of 64 patches. Moreover, the radiation band undergoes a slight change, there is increasing by 1.38% compared to that of the mono-source excitation using 16 patches. To increase the radiation bandwidth of the array antenna, a dual resonator is used. The proposed antenna shows 3.45% enhancement in comparison to a single resonator for an excitation using 64 patches. Otherwise, with a reduced number of patches (16 or 32 patches) the directivity becomes almost stable at about 20dB for the entire operating band. Furthermore, the amplitude of the back lobe decreased from 5dB for conventional monoresonator to less than -5dB using the dual resonators. [ABSTRACT FROM AUTHOR] |
