Appl. No.:

10/443510

Inventors:

Antonio Almeida - Clark NJ, US
Shankar Joshi - Warren NJ, US
Meta Rohde - Upper Saddle River NJ, US

Assignee:

Synergy Microwave Corporation - Paterson NJ

International Classification:

H11P005/08

US Classification:

333246, 333238, 333164

Abstract:

A microwave frequency device includes: a first substrate having a dielectric layer and a conductive film disposed on opposing first and second sides of the dielectric layer, the conductive film on the first side of the dielectric layer of the first substrate including at least one signal line; and a second substrate having a dielectric layer, conductive film disposed on at least one of first and second opposing sides of the dielectric layer, and at least one cut-out where the dielectric layer and conductive film have been removed, wherein the first and second substrates are bonded together to form a bonded assembly such that (i) a portion of the signal line of the first substrate is sandwiched between the dielectric layers of the first and second substrates, and (ii) the at least one cut-out exposes a portion of the signal line, thereby forming a microstrip portion. A method of forming same is also disclosed.
