Derivative antenna bandwidth of small wide electrical

摘要

A dielectric element mounted on the first side of the dielectric substrate and disposed on the first side of the substrate, the microstrip type feed extending between the dielectric element and the substrate, the substrate and a conductive layer formed on the side of the second side opposite to the first side of the dielectric antenna which is formed in the conductive layer at the position where the aperture corresponding to the position of the dielectric element is provided is. The antenna is electrically small, high bandwidth, has good gain characteristics, is efficient and does not detuned easily.
