<p>The use of a generic algorithm (GA) to design patch shapes of microstrip antennas for multi-band applications is disclosed. A full-wave electromagnetic solver is used to predict the performance of microstrip antennas with arbitrary patch shapes. Two-dimensional chromosomes are used to encode each patch shape (3004) into a binary map. GA with two-point crossover and geometrical filtering is plemented to achieve efficient optimization. The GA-optimized design are built to a solid substrate (3002), (e.g., FR-4). The patch shape (3004) may be further optimized to broaden the bandwidth at one or more of the frequencies. In addition to multiband operation in frequency, designs based on other objectives, including size miniaturization and/or circular polarization are disclosed.</p> |
