Design and Analysis of Slotted Microstrip Patch Array Antenna at 2.4GHz for WLAN

Wireless technology is one of the major area of research in communication systems. Antenna plays major role in communication system so designing and fabrication of antenna is very important for the communication system. An understanding the operation and fabrication of antennas is important as wireless technology is one of the major areas of research in communication systems. For short distance network communication widely used wireless distribution standard is WLAN (ictactjournals. in, ijates.com). In existing system such as single patch antenna has disadvantages of narrow bandwidth, low gain, low directivity and low efficiency etc. The proposed system reduces these disadvantages by implementing use of array of antennas. Microstrip array antenna optimizes overall performance of system. This system is to be cost effective, more reliable and smaller in size. Designing array of antenna is suggested using rectangular shape gives better performance in all aspects. The proposed patch antenna design has return loss of − 18.75 dB and covers 2.4 GHz frequency range. For WLAN applications this antenna offers excellent performance and a great solution.
