1. A broadband, low VSWR, double mitered waveguide bend for a hollow pipe waveguide having rectangular cross-sectional dimensions comprising a waveguide bend defining housing having two ports adapted to be aligned with the waveguide for the efficient transmission of electromagnetic energy through said housing and having impedance compensating means within said housing adjacent each of said ports, the cross-sectional dimensions of the waveguide within said housing being substantially uniform in the plane normal to the bend, the sidewall of the bend on the outside of the bend being defined by:

  • a first surface substantially coplanar with one wall of the waveguide externally of said housing adjacent one of said ports, a second surface substantially coplanar with one wall of the waveguide externally of said housing adjacent the other of said ports, and a third surface connecting said first and second surfaces, said third surface being generally arcuate away from the sidewall on the inside of the bend so that the cross-sectional dimension of the waveguide within said housing in the plane of the bend along a line bisecting the angle of the waveguide bend is greater than the corresponding dimension of the waveguide.
