Additionally, switches may be used to 'switch in' and 'switch out' capacitive elements to adjust the bandwidth of the antenna.
另外地，开关可被用来“接入”和“断开”电容性元件，以便调节天线的带宽。

For example, the switches may change the overall length of the antenna such that the frequency range of the antenna is changed.
例如，该开关可以改变天线的总长，从而改变天线的频率范围。

As one of the most important MEMS devices, RF MEMS switches have been applied in front-end circuits of some microwave systems, antenna and phase shift architectures.
