23 Jul Ultra wide band antenna
Abstract
The invention provides an ultra wide band antenna. The ultra wide band antenna mainly comprises a dielectric substrate, a main radiating unit, a zigzag microstrip feeder, an antenna ground plate and a reserved radio frequency circuit ground plate; the main radiating unit (5) is composed of an elliptic ring and a tuning stub (6); the zigzag microstrip feeder (3) is of a right-angle-shaped bent structure so as to lead a feed point to a desired position; the antenna ground plate (1) is of a trapezoidal structure; and a rectangular groove structure (4) is adopted, so that high-frequency impedance can be adjusted to match 50 ohms; and the reserved radio frequency circuit ground plate (8) is in seamless connection with the antenna ground plate. Through adopting the above technical schemes of the invention, influence of a required power supply battery (9) and a human tissue (11) on the antenna is simulated, and obtained results satisfy engineering needs.
