Antenna Resonance and Bandwidth

Antenna resonance refers to the tuned circuit consisting of capacitance and inductance. This makes the antenna have the resonant frequency, where a cancellation of a reaction between capacitance and inductance takes place. As result of this, the RF antenna acquires a resistance that comes from blend of resistance from both loss and radiation.

The factors that influence the capacitance and inductance of the antenna include its features and dimensions as well as its location. A large antenna has a likelihood of having a low resonant frequency. The resonant point of the RF antenna gives it a limited bandwidth. Operating outside the bandwidth may cause impairments to the antenna.

It is however, possible to operate an antenna beyond the stipulated bandwidth without fearing the likely damage of a set. One can also receive signals that are afar off by the use of a long wire that also helps in signal reception but one should ensure that the RF antenna is designed in a way that it will give optimal reception.
