Patent ID: 7930814

Claim:
A method for manufacturing a septum polarizer comprising: dispensing a layer of adhesive on a first contact surface of a first substrate, the adhesive having a first cure temperature; attaching the first substrate to a second substrate by: placing the adhesive layer on the first contact surface of the first substrate in contact with a second contact surface of the second substrate, thereby forming a combined structure; and elevating the combined structure to a first temperature that is above the first cure temperature for a predetermined period of time, thereby curing the layer of adhesive; after attaching the first substrate to the second substrate, applying a continuous metallization coating over each outer surface of the attached first and second substrates, the metallization coating having a second cure temperature that is lower than the first cure temperature of the adhesive; and elevating the combined structure and metallization coating to a second temperature, the second temperature being above the second cure temperature and below the first cure temperature, thereby curing the metallization coating without degrading the layer of adhesive.
