Abstract :
In this paper, a small ultra-wide antenna is proposed based on the Genetic Algorithms and MOM. The antenna is fed at the middle and lumped elements are loaded at appropriate location. The simulated and measured results indicate that the antenna has many advantages such as ultra-wide band from 30 MHz to 512 MHz, the VSWR of the antenna is below 2.5. The Horizontal radiation pattern of the antenna is almost Omni-direction, and the gain of the antenna is greater than -3.5dB in 90% working band.
