    摘要： A waveguide and an attenuation pole waveguide bandpass filter with a simple structure without any additional structure such as a negative cross coupling between resonators.The attenuation pole waveguide bandpass filter arranged at right angle to the longitudinal direction (radio wave propagation direction) is composed only of conductors. The conductor comprises depressions each opening outwardly and having a non-conducting region which continues from the inside of the opening section to the outside, and a window in the conductor section between these opposed depressions. In an alternative embodiment, such conductor shall be covered by a dielectric such as a resin.

    摘要： A low-profile antenna structure can control its directivity with great flexibility. Excited elements 11 and 12 are symmetrically arranged on a y-axis, whereas parasitic elements 13 and 14 are symmetrically arranged on an x-axis, with respect to an origin. The excited elements, as well as the parasitic elements, each have an inverted-F antenna structure and are a distance of λ/4 apart from each other. Feed circuits 21 and 22 are respectively connected to and feed signals to the excited elements 11 and 12, such that phases of the signals to be fed are different from each other by a desired degree. Variable reactors 23 and 24 (i) are respectively connected to the parasitic elements 13 and 14, and (ii) in accordance with reactance values thereof, can each change an electrical length of the corresponding one of the parasitic elements.
