# 5.2 Coplanar Discontinuities

> The Group of discontinuities consists of all usual discontinuities with and without air-bridges (see Tables 5-2a and 5-2b). There are 9 Elements in this group: Coplanar Open (C_OPEN) with and without connected ground planes, Coplanar Short (C_SHORT), Coplanar Gap (C_GAP), Coplanar Step (C_STEP), Coplanar Taper (C_TAPER), Coplanar Air-Bridge (C_AIR), Coplanar Bend (C_BEND), Coplanar Tee-Junction (C_TEE) and Coplanar Cross-Junction (C_CROSS). All junctions can have arbitrary arrangement and combination of feed lines and air bridge types at ports. The equivalent circuits used for the description of electromagnetic behavior of these elements are shown in Tables 5-2a and 5-2b.
