Summary:Provided is an antenna device, which has a transmitarray for antenna beam improvement in which radiation deterioration from stacked voids is overcome, wherein the transmitarray of a metasurface is contactably attached onto a patch array antenna, the transmitarray of the meta surface serving as an electromagnetic wave lens, and a back cover such as a cell phone cover is contactably formed on the transmitarray, and thus, there is an effect that impedance matching and antenna gain are improved by the transmitarray. 안테나 빔 향상용 적층공극의 방사열화를 극복한 트랜스밋어레이를 구비한 안테나 장치는 패치 배열 안테나의 상부에 전자파 렌즈 역할을 하는 메타표면의 트랜스밋어레이(Transmitarray)를 접촉 부착하며, 그 위에 핸드폰 커버와 같은 백커버를 접촉 형성하여 트랜스밋어레이에 의해 임피던스 정합과 안테나 이득을 향상시키는 효과가 있다.
