Abstract

The complex resonance of the circular-arc dipole antenna is studied theoretically. The Green's function technique is employed to formulate an integral equation for the dipole current, and the method of moments (MoM) is used to convert the equation into a matrix equation. An equation for the complex frequency is the obtained by enforcing the determinant of the impedance matrix to zero. From the complex frequency, the resonant frequency and Q factor of the circular-arc dipole antenna are found. The effects of the arc radius, dipole length, and dipole radius on the complex frequency are investigated and discussed.
