Analysis of Slot Loaded Patch Antenna for Miniaturization Using Slot and L Slits for Multiband Wireless Applications

Abstract:

This paper presents a microstrip patch antenna loaded with slots and slits to achieve miniaturization. The antenna is designed on FR4 substrate with a dimension of 27.1 mm  37.9 mm  2.4 mm. The antenna is introduced with six parallel slots along the length of the antenna and two L Slits along the edges achieving antenna miniaturization. A frequency miniaturization of 41.6 % with gain and radiation characteristics is achieved. The antenna exhibits good radiation characteristics with a peak gain of 6.49 dB with good directivity of 6.294 dB. The effect of increase in slot and slit length and width variation on miniaturization is presented with achieved S11 characteristics. The antenna operates as a multiuband antenna covering major wireless applications like GPS, GSM, WLAN, Bluetooth and ISM.
