Triangular microstrip patch antennas for dual mode 802.11 a,b WLAN application

The analysis of equiangular triangular microstrip patch antennas is conducted to determine the mutual coupling under the constraint of small interelement spacing. The results show that the optimum location is near the midpoint along the edge of the antenna and not at the vertices. A four element diversity antenna is designed that has dual band (2.45, 5.25, 5.8 GHz) and dual linear polarization capabilities.
