Abstract

Patch antenna with double notches and triangular tapered feeding line has been investigated. It is observed that broadband matched double-notched patch antenna is suitable for tri-band operations from simulation and experimental results. It shows a measured return loss well below 10 dB in all three-frequency bands of operation. It has also been observed that the double notched conventional rectangular microstrip fed notched antenna could not even achieve dual band operations. Besides the patch antenna design, a proper impedance matching network is required for patch antennas for multi-band operations.
