This paper proposes a multiband microstrip patch antenna covers a multiple operating frequency bands PCS/DCS/LTE/WIFI. The overall dimension of the proposed antenna is 65×67.05mm 2 printed on an FR4 substrate, having 1.6 mm as thickness with a relative dielectric permittivity of 4.4 and 0.025 for loss tangent. The proposed antenna was study and validated by using electromagnetic software's CST-MW. Three bands (1.811-1.828 GHz, 2.631-2.749 GHz and 4.554-5.457 GHz) are achieved by inserting a slot on the top patch and ground. The radiation pattern has acceptable response with low cross polarization at both E-plane and H-plane.

This work deals with desgin of  a novel  compact  Dual band PIFA Antenna structure. The proposed antenna is validated for GPS and WIFI applications. The antenna is achieved on a lossy FR4 substrate. The final size of the antenna is 100×55×13.235 mm3. The final antenna structure was optimized and validated into simulation, fabrication and test. The proposed multiband PIFA is optimized by using solts technique. The fabricated antenna is validated to cover the operating frequencies of GPS (1.535 -1.7GHz) and BLUTOOTH/WIFI (2.54-2.47GHz) bands.
