Abstract
This paper deals with the design of 2.4 GHz slotted substrate integrated waveguide (SIW) array antenna for wireless local area network (WLAN) application. The use of SIW structure is addressed to achieve a compact shape of waveguide-based array antenna especially at low frequency region. The proposed array antenna which is intended to work at the frequency of 2.4 GHz applies several configurations of longitudinal slot array on an SIW surface. A 1.6 mm thick FR4 epoxy dielectric substrate is used to deploy the design of SIW-based slotted waveguide array antenna. The performances of array configuration as well as the effect of slots number are investigated to attain the specified requirement. A 4.8 dBi gain could be achieved by a 1 × 2 slotted waveguide array antenna which has 8 slots in each array configuration.
