UWB module with antenna using organic substrates

Abstract

This paper presents the ultra wideband (UWB) module which contains an antenna, switches and a low noise amplifier (LNA). In order to accomplish small size and low cost, the antenna is designed using organic substrates and other parts are fabricated on the same printed circuit board (PCB) as the antenna. Size of the antenna is 20mm x 15mm and size of the UWB module is 20mm x 35mm. The antenna is designed by threedimensional electromagnetic (3D EM) simulator. Input VSWR and radiation patterns of the antenna are measured. Measurement results confirm that the performance of the fabricated antenna is similar to simulation results. Input VSWR is less than 1.6 at the frequency band of 3GHz to 5GHz. Data transmission rate of the module is simulated using the measured antenna parameters. Results of system simulation show that the module is useful for UWB applications. This is the first report of a UWB module with an antenna using organic substrates as far as authors get to know.
