U shaped multiband microstrip patch antenna for wireless communication system and parametric variational analysis

Microstrip patch antennas are the most common form of printed antennas. They are popular for their low profile geometry, light weight and low cost. This paper proposes a planer U shaped patch antenna in symmetric shape first and some modified form next. This paper initially proposes a new designed patch antenna in multi band and then some parametric variations are applied so that the required resonant length can be changed by which the resonating frequencies can be changed. 1^st Proposed antenna is analyzed and then a new type of Patch antenna is introduced. The proposed Antenna is designed by using substrate of Rogers RT/ duroid 5880(tm) having thickness of 0.8mm initial design, and then substrate is changed to Z paper with different substrate thickness so that multiple resonating band can be achieved with enhanced Band width of application. The antenna proposed is designed and simulated using HFSS and results like VSWR and S11 Parameter for analysis is ploted. Finally a comparative study is done to show that how number of band and operating Band Width can be enhanced for planer Antenna system.
