Multi Slotted Microstrip Patch Antenna for Multiple Wireless Applications
ABSTRACT
A multi-slotted antenna is analyzed and simulated by HFSS simulation software. Two rows of rectangular slots are introduced in the rectangular geometry to enhance radiation. Many feeding techniques are available them Micro-strip feed technique is used for this design. Hexa stands for six resonant frequencies generated by this design. Due to the concept of fractal antenna similar slots are introduced in rectangles increasing 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 the antenna are 40mm*50mm due to the size of the antenna being 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 of this antenna with dielectric 4.4 and thickness of 1.3 mm. The design is analyzed by HFSS software.
Multi Slotted Microstrip Patch Antenna for Multiple Wireless Applications
INTRODUCTION
Wireless communication is one of the most important parts of today’s world. Most of the applications like GPS, mobile phones, and Bluetooth have shown huge growth, and some other applications like LAN tagging, wireless, and wireless internet are emerging every day.
Microstrip antennas are useful as transducers that can convert EM waves into electrical signals and vice versa. These are lightweight, easy to manufacture, and small volume.
These antennas are very useful due to their multiple advantages which are light in weight, cheap in cost, low profile and easy to configure, and simple to manufacture. In today’s scenario, microstrip patches are commonly used in the following applications which are in aircraft, Satellites, and Mobile communication. The process of Antennas fabrication and designed in multi-rectangular slotted. It can be useful for (1 to 4 GHz). So it is used in most wireless communication systems like Wi-Fi and the telecommunication industry. In the last few years, there is huge development is done in the field of antenna designing and simulation by various techniques like fractal approach, multi-dielectric, etc. Another face of development in the microstrip patch antenna is a different type of cutting in the patch as well as inside the ground plane which is called defected ground structure.
