    摘要： Disclosed are exemplary embodiments of omnidirectional broadband antennas. In an exemplary embodiment, an antenna generally includes a ground element, an antenna element, and an annular patch element. The antenna element may be electrically isolated from the ground element. The antenna element may include at least one portion that is substantially conical, substantially pyramidal, and/or that tapers in a longitudinal direction. The annular patch element is electrically grounded to the ground element. The annular patch element surrounds at least a portion of the antenna element and is parasitically coupled to the antenna element.

    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.

    摘要： An antenna system for reception of channel signals form the UHF band by a receiver, including an electrically small antenna and, connected between the port connected to the antenna and that of the receiver, an active impedance matching device controlled by command signals depending on the quality of the signal received by the receiver to compensate for the impedance variations due to the environment associated with the antenna and to reject the frequencies of interfering channels adjacent to the reception channel without interfering with the active impedance matching of the antenna.
