Feb 25, 2011  Written by an antenna engineer turned professor who has worked at Apple, Nokia and Amphenol, 'Antenna Design for Mobile Devices'is a comprehensive guide for fresh and intermediate engineers involved in antenna design. The book instructs readers through all aspects of real world antenna designs. In this letter, a novel mobile phone antenna for 2G, 3G and 4G standards is presented. Based on the folded inverted-L antenna associated with a ground stub, the proposed structure can operate in.

• To design a matching network for a whip-stubby antenna which has two positions: extended and retracted.
• To design an antenna matching network that gives a balanced performance between the free space and the talking position.

To design a matching network for a cell phone antenna, many commercial software packages, such as Agilent ADS®, Microwave Office®, and so on, can be used. When I was working for the industry as an antenna engineer, I did feel, although those commercial codes were very powerful, they were not very efficient and were a kind of overkill when used in an antenna matching network designing, which normally uses less than four components. Thus I decided to write this software in my spare time. The first version was written in 2003 and I have been modifying it since then. After I made my career U-turn in 2007, the software can now be released to public.
