The rapid development of modern wireless communication technologies , reconfigurable antenna With the advantage of real-time reconfigurable antenna characteristics , a significant role to play in the development of modern communication systems , has become a hot research topic in the field of the antenna . However , this antenna technology is in the development stage , there are some issues to be further addressed . This paper, for the frequency, direction, diagrams and polarization reconfigurable antenna , several novel structural design reconfigurable antenna, antenna parameters reconstruction function are set in the proper position of the antenna structure of a certain number of PIN switch and control the switch -off state , the main work is as follows . (1) frequency reconfigurable antenna design of the two structures . One is based on the slot antenna of the microstrip structure , can be realized the antenna switch between two frequencies 1.345GHz and 1.9GHz . Another one is based on the microstrip patch antenna of the U-shaped slit , by changing the antenna structure allows the antenna has a five different working status . (2) Design of a directional pattern can be reconstructed microstrip patch antenna, the antenna main beam can be switched in both directions . Subsequently on this basis and the introduction of the two PIN switch , the antenna structure can be reconstructed at the same time one can achieve the frequency and direction of FIG . ( 3) design a circular polarization reconfigurable microstrip patch antenna , antenna switch in status between the left-hand circularly polarized RHCP .
