Title The Analysis And Design Of Dual-band Micro-strip Antennas
Abstract
Now in the information society, information transmission has been greatly developed and widely applied, the 802.11 protocol group is IEEE for wireless local area network standards, and then established the 802.11a and 802.11b two protocols, the carrier frequency of 802.11b is 2.4Ghz, the frequency rate of 802.11a is 5.2GHz, in the actual production, application device 5Ghz development up more trouble, therefore has not been widely used, the range of use of 802.11a is limited, 802.11a equipment manufacturers in order to cope with such market lack of technology, gives the corresponding improvement, at the same time, dual-frequency microstrip antenna technology becomes more and more important. There are many ways for microstrip antennas to implement double or multiple frequencies. One is the dual-frequency micro strip patch antenna; another is the printed monopole antenna. This paper firstly introduced the basic background of related antennas and general principles of these antennas and then introduced the related theory of slot antenna, after that specifically described the method about how to make a dual-frequency micro strip antenna, finally gave out the simulated results, and got some basic data. It meets the requirement of paper about 2.4 GHz and 5.2 GHz.
