Abstract
Implementation of uniform and non-uniform inputs on antenna arrays has been performed and considered two 3 × 8 multiband antenna arrays. First antenna is operating in the frequencies of 1.61 and 2.492 GHz covering the L-band and S-band frequencies which are used for RADAR applications. The second antenna is resonating at four frequencies of 1.176, 1.575, 1.6 and 2.492 GHz covering the L-band and S-band frequencies which are used for navigational applications. Stacked patch configuration is used for both antennas. Performance of the two antenna arrays in terms of gain and side lobe level is compared. Both the antennas are designed on FR4 epoxy substrate which is having a thickness of 1.6 mm. Coaxial feed has been used for antenna elements, and each element of the array is fed by an independent coaxial feed. Beam shaping mechanism is obtained with the help of uniform and non-uniform inputs. Commercial available 3D model simulator tool ANSYS HFSS has been used to simulate the antenna array.
