Abstract: A dual band printed dipole arm compact antenna has been proposed for the wireless communication systems in this paper. Proposed antenna radiates at the dual frequencies of 1.91GHz and 4.68GHz which are useful in Radiolocation and satellite mobiles. To design the antenna a low cost glass epoxy FR4 substrate has been utilised. The overall dimension of the antenna is 42mm×42mm×1.6mm. Microstrip line feed is used to feed the dipole arms. A considerable gain of 4.2dB and 2.3dB is observed at the two resonating frequencies. The antenna structure consists of three printed dipole arms of which two are useful for the resonance and the remaining arm is used to achieve proper impedance matching.
