Review of Monopole Microstrip Patch Antenna Design for Wireless Application for Handheld and Portable Device

This paper depicts a review work on all about the monopole antenna, with come reconfigurable antenna used for handheld gadgets, such as, cell phone, tablet, portable PCs and so on. The LTE is (long-term evolution) that can give mobile broadband and multimedia services better than the GSM and UMTS systems. With the development of modern wireless communications, there is an increasing demand of compact, low profile, multiband monopole antennas. Recently, Wireless Local Area Networks (WLANs) and Worldwide Interoperability for Microwave Access (Wi-MAX) is extensively being used in commercial, medical and industrial sectors. In this paper comparative analysis of different monopole antennas on the basis of size, gain, bandwidth, VSWR and efficiency for different working bands such as LTE700/2300/2500, Wi-MAX (2.4/2.5/3.4-3.6/5/5.5/GHz) and WLAN (2.4/2.7/4.2/5-6GHz) etc. are presented. As well as we see that different techniques of switching using PIN diode or copper strip In this letter different techniques for improvement of bandwidth, gain, size and impedance of monopole antenna designs are discussed.
