Design of dual band slot antenna for LAN Application
Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear. The slot size, shape and what is behind it (the cavity) offer design variables that can be used to tune performance. A simple and compact dual-band H-shaped slot antenna for wireless local area network applications is proposed. The proposed antenna is composed of an H-shaped slot on the ground plane with size of 23mm by 32mm. The substrate material is foam. The antenna is fed by micro strip at its top. The impedance bandwidth, radiation pattern and gain of the antenna were simulated. The results show that the antenna just covers the WLAN bands (2.4-2.485, 5.15-5.35, 5.725-5.825 GHz) with the gain remains steadily. The measurement of impedance bandwidth was carried out with a network analyzer. A good agreement between measurement and simulation can be observed.
