A novel micro-structure internal antenna with sputter-deposited for wireless communication applications

This research proposes a novel micro-structure sputter-deposited internal antenna for wireless communication applications. With the proposed antennas adapted micro and nano scale technology as well as sputter-deposited internal antenna covering GSM quad-band (GSM850/EGSM900 and DCS1800/PCS1900) and WCDMA dual-band (WCDMA850/1900). To present micro-structure Ni/Ag/Ni thin films overall size is 43.0times22.0times0.0015 mm

(Ni/Ag/Ni growth thickness: 15.0times10

Aringring) without feeding mechanism. The optimized tri-structure antenna results of shows satisfied performance at GSM quad-band frequency using Agilent E5071B and CTIA chamber. This investigated proposes novel structure is very promising for the quad-band mobile antenna applications and further higher frequency operation of the wireless technology.
