Abstract: An antenna structure comprises an unbalanced antenna for receiving digital video broadcasting signals. The antenna is dimensioned to fit within an electronic device, such as a mobile phone. The unbalanced antenna has a radiative element and a feed line connected to a matching circuit so as to achieve two or more resonances within a DVB-H frequency range, such as 470 to 702 MHz. The physical length of the radiative element is always smaller than λ/4 at the frequencies of interest (470-702 MHz), but the electrical length can be smaller or substantially equal to λ/4. The matching circuit can comprise one or more LC resonators depending on the number of resonances. The resonators can be series or parallel connected between the feed line and RF circuitry for processing the broadcasting signals. The antenna can be tuned to other bands above the DVB-H frequencies for use as a diversity or MIMO antenna.

Abstract: An antenna system for use in a communications device, such as a mobile phone. The antenna system has a multiband GSM antenna operating at GSM850, GSM900, GSM 1800 and GSM 1900 that has a short-circuited section located between a separate UMTS antenna and a UMTS receive diversity antenna. As such, large electrical isolation between the two UMTS antennas can be achieved. The UMTS antennas can be short-circuited microstrip loop antennas, IFA, PIFA, ILA or PILA antennas. These antennas are well-isolated antennas instead of coupled antennas. As such, the diversity antenna is well isolated from the main antenna despite its close proximity to the main antenna. Well-isolated antennas have little mutual coupling and, therefore, are easier to design than coupled antennas, because isolated antennas can be tuned independently from each other.

Abstract translation: 一种用于诸如移动电话的通信设备中的天线系统。 天线系统具有工作在GSM850，GSM900，GSM 1800和GSM 1900的多频GSM天线，其具有位于单独的UMTS天线和UMTS接收分集天线之间的短路部分。 因此，可以实现两个UMTS天线之间的大的电隔离。 UMTS天线可以是短路微带线天线，IFA，PIFA，ILA或PILA天线。 这些天线是隔离天线，而不是耦合天线。 因此，分集天线与主天线很好地隔离，尽管它与主天线非常接近。 良好隔离的天线几乎没有相互耦合，因此比耦合天线更容易设计，因为隔离天线可以彼此独立地进行调谐。

Abstract: A transceiver system having an RF front-end operatively connected to two separate non-50 ohm antennas for separately providing transmission/reception paths for 1 GHz band and for 2 GHz band. A switching module is operatively connected to each antenna for mode and frequency-range selection within each band. Each switching module has a plurality of switching elements connected to a plurality of signal paths. Matching is separately and independently provided for each signal path. The matching can be achieved by using distributed elements or lumped elements arranged in shunt or series in order to widen the bandwidth. An electrostatic discharge protection circuit is provided between the antenna feed point and the switching module. The protective circuit can also be used as a discrete matching network that can be optimized depending on the phone mechanics and dimensions.

Abstract: The invention relates to a dielectric antenna, particularly suited to portable radio devices. The feed conductor (231) of the antenna is shaped so that it at the same time in itself serves as a radiator in the same frequency range as the dielectric resonator (220) of the antenna. The resonance frequencies of the feed conductor and the dielectric resonator are advantageously arranged to be so near to each other that there is formed a united operation band. The feed conductor is advantageously located on a surface (223) of the dielectric element. The structure may also include parasitic conductors. For the antenna according to the invention, there is obtained a larger bandwidth than for corresponding antennas of the prior art. Moreover, the air gaps between the feed conductor and the dielectric element are avoided, as well as resulting changes in the electric properties.
