Abstract: A reconfigurable dual-frequency rectangular slot antenna using MEMS technology is presented. In this structure, a rectangular slot antenna is integrated with MEMS cantilever type capacitors. Simulation results show that the structure has a dual frequency behavior where both of the resonant frequencies can be reconfigured dynamically.

Furthermore, for relatively low frequency applications, such as X-band or lower frequencies, the antennas cover a large portion of the wafer. Thus the cost of an antenna, especially array antenna, monolithically integrated with RF MEMS components may be higher compared to the antenna produced on a regular substrate. Reconfigurable antenna - Wikipedia A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ...

The first technique consists of using RF MEMS switches to connect or disconnect metallic sections to the antenna in order to increase or decrease its length. In Fig. 6.10, RF MEMS switches are used to tune the frequency of a slot antenna (Van Caekenberghe and Sarabandi, 2008). When the switches change to ON-state, the slot length is reduced and ...
