Miniature stub-loaded monopole antenna at 800 MHz for FSR sensor


Simulated design and analysis of miniature stub-loaded omni-directional monopole antenna at 800 MHz for Forward Scattering Radar (FSR) sensor is presented in this paper. A miniature technique and a robust genetic algorithm optimizer have been introduced to minimize the total length of the antenna compares to a standard monopole antenna at same frequency. The desired goals arise from comparing to commercial off-the-shelf (COTS) antenna at the same frequency. A significant difference in performance between one and two stub-loaded monopole antenna have been observed. The proposed design also shows a 12% smaller in length compared to a standard monopole antenna. A better performance also has been observed but with gain less than 2dBi. With a larger ground plane, an improvement of almost 27% smaller in total length has achieved with gain improved to 5.24dBi by the proposed design.
