In this paper, broadband inverted suspended linear polarized antennas with operating frequency at 2.4GHz for Wireless Local Area Network (WLAN) application are designed. Various shapes of slot are added on the inverted suspended rectangular patch to investigate the effect of the antenna performance. The antennas are designed by using L-probe amendment with inverted suspended rectangular patch, where this approach is used to enhance the bandwidth and gain of the antennas. The simulation is done by using Computer Simulation Technology (CST) software. The bandwidths for the inverted suspended linear polarized antennas with different shape of slot are more than 200MHz, which meet broadband application. Besides, the axial ratio for each antenna is above 3dB.
In this paper, a broadband circular polarized antenna with operating frequency at 2.4GHz is proposed. The antennas are designed by using L-probe amendment with inverted patch by using suspended rectangular microstrip antenna (MSA) technique to improve the bandwidth until more than 200MHz. The characteristics of the antenna are analyzed, so that the antenna meets broadband operations at operating frequency of 2.4GHz with return loss less than -10dB. The broadband circular polarized antenna had been designed and simulated by using Computer Simulation Technology (CST) software.
