Rolled Dipole Antenna for Low-resolution GPR
(0) In this paper a rolled dipole antenna for low-resolution impulse ground penetrating radar (GPR) is theoretically investigated. The antenna is designed for transmission of monocycle pulses with duration of 5 ns (200MHz central frequency) suitable for low-resolution GPR applications. The dipole is rolled to considerably reduce it length and resistive loading with Wu-King profile is applied for suppression of late-time ringing important for GPR. Using NEC-2 as the numerical tool it is shown that the antenna radiates the pulse with no late-time ringing. Furthermore, by rolling the wires the antenna length is reduced by a factor of 4 with no evident negative impact on the antennas characteristics.
