摘要：Long Term Evolution (LTE) is currently being used in many developed countries and hopefully will be implemented in more countries. An antenna operating in LTE-3 band can support global roaming in ITU Regions 1 and 3, Costa Rica, Brazil and partially in some Caribbean countries and antenna operating in LTE-7 band are appropriate for global roaming in ITU regions 1, 2 and 3. An antenna operating at both the bands will make the place taken by the antenna in a device into half and allow roaming in all the regions mentioned above. The geometry of the current available antenna operating in LTE-3 and LTE-7 bands has a considerably large size. A dual band microstrip antenna operating in LTE-3 and LTE-7 bands is proposed in this work with notable size reduction. The proposed antenna simulation shows resonant frequencies at 1.88GHz and 2.55GHz with return loss below -10dB that covers both LTE-3 and LTE-7 bands. Design and simulation of the proposed antenna is done by IE3D Zeland software. This proposed antenna is suitable for global roaming in ITU regions 1, 2 and 3, which cover most of the world telecom network.
