Abstract:

In this paper, the proposed Ultra-Wideband RMPA is designed by introducing a new formation of modified and combined U and H shape slots in patch and two rectangular slots in ground plane in order to attain a wideband working frequencies. This Ultra-Wideband patch antenna operates between the frequency ranges of 1.92 GHz to 11.256 GHz with S11 below -10 dB which covers almost entire three different frequency bands of S (2-4GHz), C (4-8GHz) and X (8-12GHz) frequency band respectively with standard efficiency. The proposed antenna design is simulated on Zeland IE3D simulation software using Rogers RT/duroid 5880 substrate with dielectric constant of 2.2 and thickness of 1.5 mm. The total size of the proposed antenna is 42×40 mm2 and indicates worthy bandwidth of 80 MHz, 4 GHz, 4 GHz and 3.256 GHz (total 9.336 GHz) at L-band, S-band, C-band and X-band respectively. The proposed antenna resonates at 2.06 GHz, 3.36 GHz, 3.98 GHz, 5.208 GHz, 6.84 GHz, 8.66 GHz and 9.72 GHz concession UWB operation which can be used for satellite communication and radio navigation applications at low power. The same design has also been analysed by using CST Studio Suite to exhilarate the performance of the proposed antenna. The performance consideration and exploration of two separate simulation software, it can be terminated that the proposed antenna would be a superb postulant for UWB band satellite application.

Description:

Wireless communication is the fastest growing portion and most vibrant technological field in the communication industry. The first communication between humans was by sound through voice. With the expectation for slightly more distance communication came, optical methods such as smoke signals, flags and flashing mirrors were used. These optical communication has been a part of human life and is continuously evolving. Latter, in the recent modern history, the electromagnetic (EM) band spectrum, outside the perceptible region has been engaged for communication through the use of radio. Modern wireless communication i.e. using radio waves and electrical signals for communication has been around us for more than a century. Without using any link/connection like cables or wires, wireless communication is a method of transmitting message from one point to other. The communication method can be wireless or wired and the nexus used for communication can be guided or unguided. Co-axial cables and Optical Fiber cables are used for wired cables. On the other hand, there is no compulsory physical medium in wireless communication but information propagates through space. However, space only complies for signal transmission without any guidance, where the medium used in wireless communication is called unguided medium. With the favor of wireless communication, the transmitter and receiver can be installed anywhere between few meters (remote control) to few thousand kilometers (satellite communication). Which gives us pleasure, unique sense of mobility and revolutionized way to do great things. Many new applications, including mobile phones, GPS receivers, remote controls, Bluetooth, Wi-Fi, wireless sensor networks, automated car and factories, and smart homes are emerging for research where antenna is an indispensable and vivid material in wireless communication system. An antenna is an array of conductors or an electrical element that’s connected to the receiver or transmitter by propagating electromagnetic energy from the space circumambient it, in order to set up a wireless connection between two or more apparatuses. Antennas can transmit and receive radio waves in a certain direction or in all horizontal directions equally.
