A 2.4 and 5.2 GHz dual-band monopole antenna fabricated on a flexible parylene membrane for Bluetooth and wireless local area network (WLAN) modules was designed and fabricated. The measured results show a good antenna performance and agree very well with the design simulations in both return loss and radiation characteristics. Parylene is a flexible polymer film; it can be deposited on various substrates and peeled off after completing device processes as stand-alone thin-and-flexible-substrate-containing devices. Owing to its excellent physical and chemical properties such as its low dielectric constant, light weight, low conductivity, and inertness to chemicals, parylene is also suitable for fabrication of many other RF devices.

A MEMS meander monopole antenna is fabricated in the form of a folded microstrip on the upper and bottom surfaces of the substrate. This design is based on the meander line principle with a three-dimensional structure to achieve reduced size compared to many other small size printed antennas. The MEMS technologies, such as excimer laser drilling and copper electroplating were used in the fabrication of this antenna. This antenna can be mounted on the silicon wafer by anodic bonding technology. The design features 2.45 GHz operating frequency with 190 MHz bandwidth for WLAN applications. The geometric length of the antenna is 21 mm, and the width is 4 mm. Measured results have good agreement with simulation data.
