Study and Investigations of Wideband to Sub Band Frequency Reconfigurable Microstrip Patch Antenna for Wireless Applications

Abstract

In modern world, due to the high use of gadgets especially various application oriented wireless devices are rising. Numerous wireless communication devices with various functions are emerging. Handling multiple wireless communication in single device is facing severe problem. Mainly wireless device struggle on handling multiple frequency. Significantly, for wireless devices to work with multiple frequencies it requires multiple antennas which may increase the size of wireless device. Another important problem is interference of signal which are giant misfortune for wireless device to achieve required bandwidth for communication. newlineTo overcome all the difficulties an enhanced antenna design is proposed. The proposed micro strip antenna has ability to handle multiple bandwidth with single antenna. By a special size of antenna the interference of signals get reduced. To attain better bandwidth a suitable substrate with high dielectric property is used. After considering multiple literature works carefully an enhanced designed of antenna is proposed. Need of compact in size and multi frequency requirement for wireless device the micro strip antenna was designed. This antenna has an ability to handle multiple bandwidth by connecting antenna feed and ground plane with switches. Switches are used here to change the antenna radiation mode. By adjusting various mode of antenna by switches the antenna can change with different frequency. newlineThis designed microstrip antenna can handle multiple frequency with varying switching mode. The designed microstrip antenna had reduced interference by adjusting shape and size of antenna plane. Better dielectric substrate used here is FR4 which helps to attain high bandwidth. Thus this tested compact and ultra-size reconfigurable microstrip antenna is a support for recent wireless application to effectively handle multi-frequency moreover these type of microstrip antenna can be used in the field of biomedical. newline newline
