Miniaturization of array microstrip antenna using peripheral slits for wireless fidelity communication

This paper proposed a new design of array microstrip antenna using slit technique to reduce dimension of the antenna for Wireless Fidelity Communication and to increase gain. Dimension of the enclosure of the proposed antenna is 269 mm × 87 mm. The proposed antenna using single layer FR4 substrate with relative permittivity (εr) of 4.3, substrate thickness (h) of 1.6 mm and loss tangent (tan δ) of 0.0265. The simulation results shown that the antenna is capable working at frequency 2448 MHz with VSWR of 1.104 and return loss of −26.14 dB. Bandwidth of the proposed microstrip antenna is 320 MHz (2253 MHz–2573 MHz). Furthermore, its dimension can be reduced up to 37.5% with its gain of the proposed antenna of 6.45 dB.
