Abstract: 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.
