In recent years, the inventions in communication systems require the development of low cost, minimal weight, compact and low profile antennas that are capable of maintaining high performance over a wide spectrum of frequencies. This technological trend has focused much effort in the design of microstrip patch antennas because of its inherent characteristics that fits the requirements of modern communication devices. This paper presents the design and simulation of a compact rectangular slot patch antenna for dual frequency operation at 2.4 GHz and 5.2 GHz using the inset feed technique. The simulation of the designed antenna was done with the aid of computer simulation technology (CST) microwave studio version 12. The antenna has a miniature compact size of 44×41×1.6 mm3 which resonated at a return loss of -19.619 dB and voltage standing wave ratio (VSWR) of 1.303 at 2.4 GHz, and -17.55 dB and VSWR of 1.301 at 5.2 GHz. The results show that the antenna has a corresponding bandwidth of 124.6 MHz at 2.4 GHz and 119.8 MHz at 5.2 GHz. The substrate used in the proposed antenna is the flame resistant four (FR-4) with a dielectric constant of 4.4 and a loss tangent of 0.023. The proposed antenna may find applications in wireless local area network (WLAN) and Bluetooth technology.
