| Abstract: | This paper presents a frequency-reconfigurable antenna which is controlled by two PIN diode switches.The structure of antenna is simple and compact.A wide slot antenna is loaded with switches,and the switches are easy to be controlled.When the switches turn on,the measured center frequency is 5.34 GHz,the antenna has a relative bandwidth of over 70% and the reflection is less than-20 dB.When the switches turn off,the measured center frequency is 2.4 GHz,it has a relative bandwidth of 2.01% and the reflectio... |
