Tightly-coupled dipole antenna with common-mode resonance suppression

A method of suppressing common mode resonance of a dipole antenna, the method comprising:

• generating a circuit load representation of dipole arms of the dipole antenna, including an inductance and capacitance substantially matching the inductance and capacitance of the dipole arms;
• simulating connection of a first end of the circuit load representation to a first conductor representation and a second end of the circuit load representation to a second conductor representation, wherein the first conductor representation and the second conductor representation substantially match a length of conductors of the dipole antenna;
• simulating a short across the first conductor representation and the second conductor representation to form a closed circuit;
• determining a parallel admittance across the circuit load representation;
• and
• determining, based on the parallel admittance of the circuit load representation, a common mode resonance frequency of the dipole antenna.

A method comprising:

• receiving a radio frequency signal by a dipole antenna;
• generating, based the radio frequency signal, a current through a first conductor and a second conductor of the dipole antenna;
• and
• suppressing a common mode resonance frequency associated with the current using an inductor, wherein the inductor is connected to an end of the first conductor and an end of the second conductor.
