Microstrip antennas consist of a patch of metallization on a grounded dielectric substrate. The conducting patch can
take any shape, but rectangular and circular configurations are the most commonly used configurations. The narrow bandwidth
of microstrip antenna is one of the important features that restrict its wide usage. But triangular patch is used more because of
their small size compared with other shapes like the rectangular and circular patch antennas. This report presents techniques for
improvement in bandwidth. The maximum bandwidth can be achieved by controlling the distance between the two patch antennas
and by adjusting the length of the transmission feed line 50 Ohm. In this report a new geometry of “Air Gapping Concept” is
proposed. By this proposed method the bandwidth is improved 8.46% to 14.94% at the range of 2.5 GHz to 5.4 GHz which can be
used for Wireless LAN applications.
