In this research paper, a typical single-band microstrip patch antenna with circular slot on rectangular microstrip patch forming a simple and efficient technique of design has been introduced for the betterment of bandwidth and impedance matching, also, giving the same performance at the desired resonant frequency. The design is achieved by cutting single circular slot at the radiating element of the patch antenna. The proposed configurations are simulated using the HFSS software package, where return loss, input impedance (Z-parameter), and radiation patterns are used for the analysis of the different configurations. Compared to the conventional rectangular patch antenna slot loading antennas have good return loss, for these reasons we have associated the two techniques simultaneously in the same patch antenna for benefit. The proposed antenna shows the advantages in terms of low fabrication cost, constant radiation characteristics and hence suitable for multiple wireless applications like WLAN/Bluetooth. The study presents an investigation of the effects of without or with circular shaped slots (cut) can be used to improve the performance of a simple patch antenna operating in Wireless Local Area Network (WLAN) frequencies (2.4 Ghz).
