Microstrip Slot Antenna for Mobile Base Station.
A multi-band dual-polarized microstrip slot antenna for mobile base stations is proposed.The antenna is operating at the bands of GSM900(0.87-0.96)GHz,DCS1800,PCS1900,and UMTS2100(1.71-2.17)GHz used in mobile base stations.It is fabricated using the low cost FR4 dielectric substrate.The antenna is based on two orthogonal diamond cross slots etched on the ground plane and incorporates a two orthogonal microstrip feeding lines placed underneath the FR4 substrate material on the opposite side of the ground plane to achieve dual polarization.The measured isolation characteristics for the proposed antenna between the two ports do not exceed-30dB within the operating bands.The front-to-back ratio is greater than 17dB at GSM900,20dB at both DCS1800 and PCS1900 and 14 dB at UMTS2100.Average antenna gains about 7.9dBi and 7.1dBi have been obtained for lower and upper bands,respectively.The design is dedicated to the single array element which will be incorporated in an array in order to construct the base station antenna.
