Cross Slot Loaded Proximity Coupled Equilateral Triangular Microstrip Antenna for Enhancing Bandwidth

Mahesh C P | P M Hadalgi

Abstract: A new design of a slot-loaded proximity coupled equilateral triangular microstrip antenna for quad-frequency operation is presented. Results show that, by loading a cross slot centered in the triangular patch and oriented parallel to the patch's center line, a quad-frequency operation can be achieved between 2.83 GHz to 8.62 GHZ. The bandwidth has been enhanced to a maximum value of 21.96% in comparison to that of conventional microstrip antenna which resonates at 3 GHz with bandwidth of 6.97%, by introducing a cross slot on the patch. The antenna exhibits broadside radiation characteristics. The results are presented and discussed. This antenna may find applications in WIFI IEEE 802.11, IMT (International Mobile Communication) and in radar systems.
