Design of compact stacked-patch antennas on LTCC technology for wireless communication applications

Stacked-patch antennas on LTCC (low temperature cofired ceramics) multilayer structures can be easily designed for optimal bandwidth performance by an adjustment of the number of LTCC layers. This paper presents a methodology suitable for the design of compact broadband antennas. It is demonstrated that a stacked-patch antenna on an LTCC substrate with a thickness of less than 0.03/spl lambda//sub 0/ can achieve a bandwidth of up to 7%, which may find applications in a number of wireless communication systems.
