Abstract: An eight shaped annular ring slot antenna array is presented. Feed is designed with T shaped Power divider and quarterwave transformer is used. Antenna element is comprised of two linked annular slots to achieve high band width. Analysis is carried out with HFSS simulation software. Array is configured with corporate feed structure. It has been observed tha gain is increased to 4dB to 5dB and return loss band width increased from 600 MHz to 1.2 GHz around 55%, Cross polarization level also significantly decreased.
