Описание:The resulting antennas operate over two wide bands from (824-1300) MHz and from (1710-2170) MHz, covering five cellular bands (GSM850/900/1800/PCS1900 and UMTS). Cases with different antenna dimensions also have been investigated for the coupling affection. The antenna was designed by a High Frequency Structure Simulator, HFSS, built and verified. These devices need to be able to be operating with several different mobile phone systems and in different frequency bands. Based on the evolution in the wireless industry, the handsets need also to be equipped with other wireless functionality such as WLAN, Bluetooth, and GPS. In recent years, the mobile phone manufacturers have increasingly focused on thinner and more mechanically mixed products. In order to work in multi-band wireless systems, the design of the mobile phone antenna becomes a key issue. Based on the work by Vilanen et al. , a small, low profile and efficient coupling element based antenna with penta-band operations for the use in mobile telephones has been studied in this book.

The World is Flat

We call ourselves 'the thumb people.' Young girls in high school can now move their thumbs faster than they can type on a PC.” By the way, I asked, what does the “Ubiquitous Department” do? “Now that we have seen the spread of the Internet around the world,” answered Mitsuishi, “what we believe we have to offer is the next step. Internet communication until today has been mostly between individuals-e-mail and other information. But what we are already starting to see is communication between individuals and machines and between machines. We are moving into that kind of phenomenon, because people want to lead a richer lifestyle, and businesses want more efficient practices... So young people in their business life use PCs in the offices, but in their private time they base their lifestyles on a mobile phone. There is now a growing movement to allow payment by mobile phone. [With] a smart card you will be able to make payments in virtual shops and smart shops. So next to the cash register there will be a reader of the card, and you just scan your phone and it becomes your credit card too... “We believe that the mobile phone will become the essential contrailer of a person's life,” added Mitsuishi, oblivious of the double meaning of the English word “control.” “For example, in the medical field it will be your authentication system and you can examine your medical records, and to make payments you will have to hold a mobile phone ...»
