Design of a simple slotted Rectangular Microstrip Patch Antenna for Bluetooth Applications G.Vyshnavi Devi, K.Pramodh Kumar , V. Rama Krishna
Department of ECE, St.Ann’s College of Engineering and Technology, Chirala, Andhra Pradesh, India. ---------------------------------------------------------------------***--------------------------------------------------------------------demand for antennas with low cost, low profile and size, patch antenna is proposed for Bluetooth applications at ease of fabrication and ease of integration with the 2.41GHz frequency with coaxial feeding technique. The patch is parent device. Microstrip patch antennas are widely used Rectangular shaped with slots on the patch. The proposed antenna resonates at 2.41GHz meeting the requirements of for many wireless applications due to their light weight, Bluetooth applications. The proposed antenna is designed on a compactness, easy to integrate and ease of fabrication. Rogers TMM 4(loss free) substrate with an overall size of 58.53 Due to these advantages, microstrip antennas are widely mm×56.53 mm. The important parameters like S11 parameters, VSWR and radiation pattern of the proposed antenna are used for the current wireless applications. Microstrip presented. patch antenna are used for mobile phones, satellites, radio, radars, global positioning system (GPS), television, Key Words: Patch antenna, Bluetooth, S11 parameters, multiple input multiple output (MIMO), radio frequency Radiation pattern. identification (RFID),medical imaging and guidance of missiles are few examples of the military and industrial 1.INTRODUCTION applications. The first Microstrip Patch Antenna was Microstrip antennas are designed to have many reported by Deschamp [1] and the first experimental geometrical shapes and dimensions but rectangular and study of Microstrip Patch Antenna was reported by circular microstrip patches have been used in many Howell [2]. However, the microstrip patch antennas offer application. The microstrip patch antenna consists of narrow impedance bandwidth and numerous techniques conducting patch on a ground plane separated by have been investigated and reported to enhance dielectric substrate. With the help of slots, the size of impedance bandwidth. These techniques include microstrip patch antenna has been reduced. This effect employing slot at the patch antenna such as the squarehas been done by changing the path of the current. When ring slot [3] and U-shaped slot [4] etc.. Other methods to the slots are cut on the patch the path of the current is increase the operation bandwidth of antennas include changed. Current travels extra path as compare to the meandered ground plane [5], electromagnetically coupled without slot of microstrip antenna. With this concept the stacked patch [6], patch antenna with integrated band size of the antenna is reduced i.e. small size antenna has pass filter [7], gap-coupled feed[8] and optimally designed been used at lower frequency. The operation principal of impedance matching network [9,10] etc. However, these the antenna is investigated using the coaxial feeding techniques follow increased system cost and complication technique. The conducting patch can be taking any shape of the system. but rectangular shape configurations are the most length In the present work, a slotted Rectangular of the antenna is nearly half wavelength in the dielectric, microstrip patch antenna is proposed. This antenna which governs the resonant frequency of the antenna. resonates at 2.41GHz which is used for Bluetooth The Bluetooth technology provides a means of applications. It produces a return loss of -15.90 dB and short range of wireless connections between electronic VSWR of 1.38. In section 2, the proposed antenna devices like mobile devices, computers and many others geometry is presented. In section 3, the simulation results thereby exchanging data, voice, and video. The rapid are presented. In section 4, the parametric study of the increase in communication standards has led to great
