Abstract
Abstract-Local Area networks work in frequency ranges 900 MHz, 3.6 GHz, 4.9GHz, 5 GHz, 5.9 GHz, 6 GHz and 60 GHz. It supports broadband communication and provides end to end communication without any propagation delays. For establishing LAN network, antennas are employed to transmit and receive signals. But the existing antenna designs for wireless LAN cannot accommodate higher bandwidths even though they provide good gain. Microstrip patch antennas are considered as they have high compatibility rates, low volume and are easy to manufacture. This paper proposes the design of a microstrip patch antenna with effective bandwidths at 1 GHz and 2.4 GHz using microstrip feed technique with dielectric materials such as FR 4 Epoxy, Arlon 450 and Taconic35. The results are shown in graphical format and have been tabulated. From the results we can conclude that FR 4 Epoxy with 1.6 mm substrate height has given best results among Taconic 35, Arlon 450 and FR 4 Epoxy. From the results we can conclude that we have achieved better bandwidths when compared to the previous works available.
