<p><P>PROBLEM TO BE SOLVED: To provide a further miniaturized nondirective vehicular fractal antenna by improving spatial efficiency by using a pattern of a fractal structure, by reducing signal attenuation even in any direction of the front-rear and the right-left, by generating a resonance frequency of a wide band by compensating for a capacitance value. <P>SOLUTION: This vehicular fractal antenna includes first and second radiation elements obliquely, laterally and oppositely arranged in an upper narrow-lower wide shape inside a ray dome for protecting the antenna, and first and second parasitic elements obliquely, laterally and oppositely arranged in an upper narrow-lower wide shape by respectively separating in parallel at a specific interval from the first and second radiation elements in an inside space for forming the first and second radiation elements. The first and second parasitic elements are arranged in the inside space which is formed by the first and second radiation elements and the radiation elements and the parasitic elements are coupled mutually. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
