Multi Rectangular Slotted Hexa Band Micro-strip Patch Antenna for Multiple Wireless Applications

A multi rectangular slotted antenna is analyzed and simulated by FEKO simulation software. Two rows of rectangular slots are introduced in the rectangular geometry enhance radiation. Many feeding technique are available out of them Micro-strip feed technique is used for this design. Hexa stands for six resonant frequencies generated by this design. Due to concept of fractal antenna similar slots are introduced in rectangle increases the current length and discontinuity. This design is useful for six band applications. The value of return loss is less than -10 dB in all six bands with acceptable bandwidth. Frequencies of resonance are 0.27GHz, 1.7GHz, 3.3GHz, 2.7GHz, 3.5GHz and 4.3GHz their respective return loss are -53dB, -31dB, -36dB, -16dB, -31dB and -25dB. Dimensions of antenna are 40mm*50mm due to this size of antenna is small which makes it portable. The values of VSWR are close to two for respective frequencies which is useful for operating frequency range. FR4 substrate is used for the design and analysis for this antenna with dielectric 4.4 and thickness of 1.3 mm. The design is analyzed by FEKO software based on Method of Moment.
