A DUAL SLOT CIRCULAR PACMAN PATCH ANTENNA FOR MULTIPLE BAND APPLICATIONS

In this paper, a circular patch antenna with dual slots has been proposed for multiple band applications. The proposed Pac-man antenna operates in C ,S and X bands of RF spectrum. The antenna has been designed and analysed for FR4 substrate with dielectric constant of 4.6. This antenna can be used for Wireless local area network (WLAN-2.5 GHz) applications, radar applications (x band) and Wi Max, wide area WiFi, 4G-LTE applications (C band). Furthermore, an alongside comparison of the proposed system with the existing circular patch antenna is demonstrated to check the accuracy of the proposed antenna. This design has been proven to enhance the bandwidth and extend the operation to multiple bands due to the presence of ‘L' shaped slot in the patch. Also, the proposed design is analysed in terms of Voltage Standing Wave Ratio (VSWR), gain and radiation pattern
