Enhanced Bandwidth Proximity Coupled Equilateral Triangular Microstrip Antenna Loaded with Horizontal Rectangular Ring Slot
In this communication proximity coupled equilateral triangular microstrip antenna consisting a horizontal rectangular ring shaped slot for quad band operation is designed and its performance is calculated with reference to conventional antenna. The proposed antenna operates between 2.71 to 8.66GHz at four different frequency points. The antenna shows enhancement in bandwidth with broadside radiation characteristics has been achieved. The design concept of the antenna is given and experimental results are presented and discussed. This antenna will be useful for IMT, WLAN (Wireless Local Area Network) and SAR (Synthetic Aperture Radar).
