In this paper a novel printed monopole antenna for CDMA and GSM frequencies is proposed. The given antenna is composed of a rectangular patch monopole printed antenna having three rectangular slots, of different dimensions, in decreasing order of area. The antenna is designed for CDMA 800 and GSM 900 standard. It covers the frequency range of both above standard, 824-894 MHz for CDMA 800 and 890-960 MHz for GSM 900, with resonant frequency of 878 MHz having -41.5dB return loss and VSWR < 1.5. A rectangular ground structure is used for minimizing the return loss. The 50 ohm probe feed is used to fed the proposed antenna.
