Multi band microstrip slot antenna for mobile base station

In this paper, a multi-band dual-polarized transceiver microstrip slot antenna with dual feed is presented. The antenna is suitable for operation in mobile phone base stations. The antenna operating bands are (0.792 - 0.979) GHz, (1.74 - 2.2) GHz and (2.4 - 2.68) GHz. The antenna support GSM, DCS, PCS, UMTS, ISM and LTE. The proposed antenna shows good reduction in area and height by 37.46% and 92.78%, respectively compared to other one´s with an isolation more than 29 dB between ports. The antenna is based upon two orthogonal cross slots etched on the metallic ground plane and incorporates a simple single layered feeding technique to achieve dual polarization radiation with an isolation more than 29 dB between them. The effort was directed towards the design of a single standalone antenna; however, the performance would be better when it is incorporated as an array element. Also, the experimental results are compared to the simulated results. Very good results are obtained.
