ANTENNA USING THE ABSORBER BASED ON META-STRUCTURE

摘要

An antenna using an absorber based on a meta-structure and an antenna for a repeater using the same are disclosed. A patch antenna of the present invention comprises a main patch, one or more electronic wave absorbers arranged around the main patch, a first resonance frequency generation unit directly connected between the input end and the output end, and a second resonance frequency generation unit connected to the output end in parallel. An effective permeability or an effective permittivity of the absorber includes a sound value in a specific frequency band. Therefore, the size of the patch antenna is minimized, and isolation between the donor antenna and the service antenna is improved.
