In this paper, broadband circular polarized antenna with different slot configuration are designed and investigated. The proposed antennas are designed at 2.4 GHz for Wireless Local Area Network (WLAN) application. The antennas are designed by using L-probe amendment with inverted rectangular patch. This technique is used to improve the bandwidth and gain of antenna. The effects on the antenna performance are investigated for the configuration of rectangular and triangular slot that embedded on the inverted rectangular patch. The inverted rectangular patch is embedded with two circular slots which are parallel with each other. The position of the circular slots is altered to determine the orientation of circular polarization. The simulation is done by using Computer Simulation Technology (CST) software. Each inverted suspended circular polarized antenna is achieved bandwidth more than 200 MHz and meet broadband application. The axial ratio for each circular polarized antenna is below 3 dB.
