일반적으로 이동통신기기 및 휴대용 컴퓨터에서 통신을 수행하기 위해서는 송수신 장치가 필요하다. 현재 이러한 통신기기에서 사용하고 있는 송수신 장치는 주로 블레이드(blade)형 안테나를 사용하는데, 이러한 안테나는 통신기기의 외부에 장착하게 되어 통신기기의 크기 및 중량이 상당히 증가시키는 단점이 있을 뿐만 아니라, 제한된 정보만을 송수신하거나 송수신 능력을 향상시키기 이해서는 안테나를 더 크게 하여야 하는 문제점이 있다. 이로써, 인터넷을 사용하여 정보를 무선송수신하는 휴대용 컴퓨터의 크기 및 중량을 증가시키고 안테나를 취급하기가 불편한 점이 지적되고 있다.In general, a transceiver is required to perform communication in a mobile communication device and a portable computer. Transceivers currently used in such communication devices mainly use blade-type antennas. These antennas are mounted on the outside of the communication device, which not only increases the size and weight of the communication device, but also has a limitation. In order to transmit or receive only information or to improve transmission / reception capability, there is a problem that the antenna must be made larger. As a result, it is pointed out that the size and weight of a portable computer that wirelessly transmits and receives information using the Internet and that it is inconvenient to handle the antenna.

또한, 위성 통신용 휴대 전화기는 기존의 지상기지국 연결 전화기 보다 훨씬 무겁고 부피가 커지게 된다.In addition, cellular telephones for satellite communications are much heavier and bulkier than conventional ground-base station-connected telephones.
