Binomial Array of Three Elements Microstrip Antenna for Sidelobe Reduction
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2019, Vol 14, Issue 1
Abstract
A binomial array of 3-elements rectangular microstrip patch antennas has been designed and simulated at 2.4 GHz using HFSS (high frequency structure simulator) software for the side lobes reduction and gain improvement. This array of 3-elements is also designed to reduce the size of the array by a pair of inner elements of a binomial array of 4-elements of rectangular microstrip patch antennas is replaced by a single element. This array is a non-uniform array because the currents in these 3-elements of the array are not equal. The microstrip feed lines are designed for the non-uniform amplitude excitations. The simulated results are compared with published results in reputed journals. The simulated result of side lobe is -7.57 dB which is negligible. The beam width of the main lobe is 300 and the gain is 14.04 dB. Other characteristics like radiation pattern (2D and 3D), scattering parameter (S11), and bandwidth have also been presented. This array can be used for the various applications like surveillance radar, mobile communication, satellite communication etc.
