antenna design book

Recently saw a classmate in order to enhance the mobile phone GPS signal, the antenna DIY to the outside, pulled a very long antenna, their own in the suspicion that this is in line with the principle of antenna design, can really make the signal enhancement? So find the following article to learn.1. RFID Fundamentals

the inverted F antenna, multi-frequency resonance is achieved by means of Slotting and adding support segments. However, to implement multi-frequency operations, the introduced structure is often complicated. Based on this, we have designed a micro-band antenna that can work in WLAN (2.4 GHz and 5.8 GHz) and WiMAX (3.5 GHz) at the same time. The antenna uses thr

The essentials and patterns of software design (version 2nd) is the book on software design and design patterns published by Zhang Yi of garden in April this year. I got it in late May and read a chapter every night, after reading chapter 28 of the book on and off last night

Article Description: This thinking about e-book design stems from a recent experience and discussion of usage. Accustomed to the Kindle Physics key flip-screen reading, the Kindle touch of the screen operation is very unaccustomed (contact evoked), or even startled! Do not like E-books, in addition to not be free to write painting, the bigger problem is that e-books can not give the same experience as tradi

modified the class it belongs to.Strategy: Define a series of algorithms, encapsulate them one by one, and make them interchangeable with each other. This mode allows the algorithm to be changed independently of the customer using it.Templatemethod: Defines the skeleton of an algorithm in an operation, and delays some steps into subclasses. Templatemethod allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm.Visitor: Represents an oper

"Design Mode" (GOF): Not recommended for beginners to see. These four are PhD levels, they are the first to propose design patterns, high theoretical level, although a thin one, but the text is relatively obscure, but also lack of easy to understand examples. When you get to a certain level, if you are interested, you can look at it."Head First design mode": Good

Finally, I have read Mr. Zhang Yi's book "Essentials and patterns of software design", and I am deeply impressed by his understanding and explanation of software design, I have a new understanding of the software design process and the use of the model. Therefore, I think of this b
