In this paper, the authors present a defective ground plane wide band slotted patch antenna designed to detect partial discharges emitted from underground LV power cables. Two slots are incorporated into the patch antenna and band width expansion was investigated by the currents flowing through the patch antenna. The antenna design simulation was carried out in the Agilent Advanced Design Systems (ADSs) environment. The fabricated antenna on FR4 substrate indicates an impedance bandwidth of 40.84% at 284.4 MHz center frequency with return loss of -37 dB. The simulated and measurement results of the antenna designed are discussed.
