Bridged ´V´-shaped patch antenna for dual-band communication

A bridged `V`-shaped patch antenna has been designed and fabricated for dual-band communication. The dual-band operation is obtained by placing a bar connecting the two arms at the top of a `V`-shaped microstrip antenna. Comparison of the return loss performance of a single `V`-shaped antenna and the bridged `V` antenna is carried out. Free space radiation pattern measurement is carried out for the bridged `V`-shaped antenna to ascertain the effect of the bridging on the far field pattern. The measured results of the bridged `V`-shaped antenna shows good performance of a dual-band operation with the potential of communicating in two different directions.
