A Connected E-Shape and U-Shape Dual-Band Patch Antenna for Different Wireless Applications

In this paper, dual operation E-shape and U-shape Patch Antenna feed by transmission line is presented and study the effect of antenna dimensions length (L), width (W) and substrate parameters relative dielectric constant(Er), substrate thickness on radiation parameters of Band width. The proposed antenna is designed on two-layer, one RT/Duroid 6006 laminate substrate and another ground plane with an area of 33 mm by 42 mm. This paper contains designing a Connected E-Shape and U-Shape Dual Band Patch Antenna for different wireless applications except for its narrow band width. The dual operation frequencies are 2.46 GHz and 4.9 GHz. A (-8 dB) bandwidths of return loss S characteristic for the dual band are 13.02 % and 3.28 % respectively. This connected U-shape & E-shape patch antenna is mainly applicable to wireless local area net-works (WLAN).This paper suggests an alternative approach in enhancing the band width of microstrip antenna for the wireless application operating at a dual frequencies 2.46 GHz and 4.9 GHz. The measured results have been compared with the simulated results using software GEMS version-7.0.
