Micro Strip Patch Antenna for WLAN/WiMAX Applications: A Review

Abstract

The increasing demand for good wireless antennas in the field of wireless communication leads to the advancement in the design and development of compact microstrip patch antenna. This paper reviews the development of multiband microstrip antennas for WiMAX and WLAN applications in recent decades. Multiple advancements have been done till date in the field that includes different sizes of patches, ground plane, multiple sizes of slots (L-shaped. Rectangular, Circular shaped) have also been used to get required multiband frequencies. Dual-Band Monopole Patch Antenna Using Microstrip Fed technique was considered due to its satisfactory frequency bands with a very compact size-Slotted Microstrip Fed Monopole Antenna for Triple Band was implemented for improvement in radiation efficiency, Compact CPW-fed tri-band printed antenna with meandering split-ring slot that was considered for multiband applications , ,Miniaturized printed K shaped monopole antenna with truncated ground plane design was another technique considered for improved radiation efficiency and simple design ,Dual Band Monopole Antenna for Wlan 2.4/5.2/5.8 with Truncated Ground was considered for an accurate omnidirectional radiation pattern and comparatively high radiation efficiency, Miniaturized Pi (Π) - Slit monopole antenna for 2.4/5.2/5.8 applications was then studied for its simple and compact design. Frequencies. All these design approaches will be reviewed and discussed in this paper.
