摘要： A band-pass filter for a wireless communications signal is provided. The band-pass filter includes a first element and a second element that mates with the first element to form a waveguide. The formed waveguide comprises a first linear segment and a second linear segment coupled by a first angular bend. The band-pass filter further includes an insert plate disposed between the first element and the second element along a direction of propagation of the waveguide. The direction of propagation follows the angular bend in the waveguide. In some embodiments, the band-pass filter is an E-plane filter. In some embodiments, the band-pass septum filter has a shorter length along an x-direction than a straight septum filter with the same performance.

摘要： A transmission line with a bending portion is provided, which line comprises any one of a coplanar line, another coplanar waveguide line formed on the dielectric substrate under which a ground layer is provided and a coplanar strip line. A chamfered portion is provided on the outer angular portion of the bending portion of the signal wiring conductor and a triangular conductor is disposed to an inner angular portion thereof. Given that length of the chamfered portion is defined as a, and length of the wiring edge side of the triangular conductor is defined as b and width of the signal wiring conductor is defined as c, it is arranged such that a is greater than b+c×square root of 2. Thereby, a transmission line or an optical module of smaller reflection loss at the bending portion thereof and of improved high-frequency characteristics is provided.

摘要： A dielectric transmission line bend structure includes an electrically conductive strip that forms a bend (e.g., a right angle bend). The inner edge of the bend includes a plurality of curved and/or straight line segments that result in the inner edge extending along a circuitous path in order to thereby reduce transmission line loss. A T-type junction includes a first or left side inner edge bending to the left and a second or right side inner edge bending to the right, with both inner edges including segments that result in greater inner edge lengths in order to increase current path lengths along the inner edges and thereby help reduce transmission line loss. A method of designing a transmission line bend structure includes the step of providing a preliminary bend structure design having an electrically conductive strip with at least one inner edge extending along a circuitous path between first and second inner edge end points on the strip. The method proceeds by producing simulation information indicative of transmission line loss characteristics of the preliminary bend structure design, and adjusting the length of the circuitous path according to the simulation information in order to produce an final design having improved transmission line loss characteristics.
