Tri-Band Rectangular Patch Antenna with C Slot

A tri-band rectangular patch having C shaped slot with a strip with partial ground plane is proposed. The antenna is fed through 50 ohm inset feed. The antenna occupies the size 38mm x 49mm. Triple band is achieved due to the strip slot attached with C slot and Partial Ground Structure (PGS). The antenna covers the 2GHz, 3.6GHz and 7.2GHz bands with impedance bandwidth 390MHz, 430MHz and 360MHz respectively. The simulated and measured results show good antenna performance for multiple applications in wireless communication.
