ANTENNA DEVICE

摘要

Disclosed is an antenna device. The device comprises: a dielectric substrate, comprising a first surface and a second surface opposite the first surface; and an antenna unit, comprising a first resonance frequency band unit and a second resonance frequency band unit, and disposed on the surface of the dielectric substrate. Compared with the prior art, the dual-band antenna resonates at frequency bands of 880-960 MHz and 1710-1880 MHz, and the dielectric constant and dielectric loss of the dielectric substrate are lowered by introducing polar and non-polar polymers, so as to reduce the power loss and improve the energy conversion efficiency of the antenna device. In addition, comprehensive performance such as the gain of the antenna device is further improved by antenna selection and optimizing the antenna selection design.
