Non-Volatile RF Frequency Reconfigurable Antenna for Wireless Communication

This paper presents the design, fabrication, and measurement of a frequency reconfigurable antenna by using non-volatile RF switches. The non-volatile switches were made by Nafion and glued to the antenna using silver epoxy to make it frequency reconfigurable. Due to the nature of their non-volatility, these switches do not need any DC power to sustain their states hence dissipate zero static power, significantly reducing the power consumption for antenna operation. The antenna can switch at three different operation modes between 1.8 GHz to 3.5 GHz without any static power supply.
