Abstract
A triple rectangular slotted microstrip patch antenna is designed and investigated with and without slot using CST Software. By using the triple rectangular shaped slot the designed antenna operates at 2.4GHz (ranging from 2.3704 GHz (Gigahertz) to 2.4391 GHz at -10dB return loss) for WLAN (Wireless Local Area Network) and 3.6GHz (ranging from 3.5643 GHz to 3.6548 GHz at -10dB return loss) for WiMAX (Worldwide Interoperability for Microwave Access) applications having a maximum return loss -28.5dB and -25.4dB respectively. For the design of this antenna we have chosen FR-4 (lossy) as substrate having permittivity 4.3. The designed antenna has appreciable values of gain and directivity at both the frequencies. The proposed antenna works on the principle of excitation of the slots at the operating frequencies. The antenna was designed keeping in mind the two major Wireless standards i.e., WLAN and WiMAX bands of frequencies. The proposed triple-rectangular slots are unique in terms of its construction and have appreciable results at the operating frequencies.
