    摘要: A method for propagating signals with an automatically-tuning antenna uses an ultra-wideband antenna formed from a coaxial cable passed through the center of a conductive tube. The center conductor of the coaxial cable is connected to an end of the conductive tube, and the shield of the coaxial cable is not electrically connected to any conductor. Two ferrite beads are disposed serially on the cable beneath the tube, spaced apart from the tube and spaced apart from one another. A centering spacer maintains the coaxial cable within the center of the tube. An electrical signal is applied to a proximal end of the coaxial tube. The antenna is automatically tuned as the frequency of the electrical signal changes, without a need to reconfigure the physical components of the antenna.

    摘要: The invention discloses a LTCC wide stopband filtering balun based on discriminating coupling. The filtering balun includes a dielectric, and a first resonator, a second resonator, a first feeding line, a second feeding line, a third feeding line and a metal ground which are arranged inside the dielectric. The two resonators are both half-wavelength resonators distributed on different layers, and the layers are connected through metal through holes. the first feeding line is coupled with a specific area of the first resonator for performing feeding to suppress a second harmonic, and the second feeding line and the third feeding line are coupled with a specific area of the second resonator for performing feeding to suppress a third harmonic, thus realizing a wide stopband filtering performance. The second feeding line and the third feeding line are symmetrically arranged about a center of the second resonator, thus realizing a same-amplitude reverse-phase balun output characteristic. The LTCC wide stopband filtering balun based on discriminating coupling according to the invention can suppress the second harmonic and the third harmonic, and a LTCC multi-layer circuit technology used reduces a size of a filtering balun.

    摘要: In one example an apparatus is provided. The apparatus includes a low frequency radiator, a high frequency radiator, a high frequency waveguide that carries high frequency bands to the high frequency radiator, a low frequency coaxial waveguide coupled to the high frequency waveguide in a coaxial structure, wherein the low frequency coaxial waveguide carries low frequency bands to the low frequency radiator and a low frequency combiner in communication with the low frequency coaxial waveguide, wherein the low frequency combiner comprises a circular low frequency waveguide and air dielectric transmission lines formed by air channels formed above and below a plurality of printed circuits in a metal housing.
