摘要： A small ultra wideband (UWB) antenna designed to have a unidirectional radiation pattern is disclosed. The UWB antenna includes a substrate; a power feeding part, provided on an upper surface of the substrate, for receiving a supply of an external electromagnetic energy; a dipole radiator excited by the electromagnetic energy fed through the power feeding part and radiating electromagnetic waves in one and the other directions of the substrate; and an active loop radiator excited by the electromagnetic energy fed through the power feeding part, respectively enhancing and canceling the electromagnetic fields produced in one or the other directions of the substrate by the dipole radiator.

摘要： An active antenna capable of transmitting and receiving a wireless signal of a low frequency band and a mobile communication terminal having the active antenna, are provided. The active antenna includes an antenna element which transmits and receives a wireless signal, a filter which filters the wireless signal being received at the antenna element such that a wireless signal belonging to a frequency band lower than the operating frequency of the antenna element is passed, and an amplifier which amplifies the wireless signal being passed through the filter. As a result, the size of the antenna can be greatly reduced, by the use of an active antenna which receives wireless signals of low frequency bands. Additionally, a more compact mobile communication terminal can be provided, because wireless signal of both high frequency bands and low frequency bands can be transmitted and received at one antenna.
