A New Strategy to Design Microstrip Antenna Array With Low Side-Lobe Level and High Gain
IEEE Access, 2019 A new strategy for designing low side-lobe level (SLL) antenna array is presented. This strategy utilizes special arrangement of antenna elements rather than direct tapered excitation amplitude to obtain an equivalent desired amplitude distribution in ...
