Antenna Design for Portable Applications in LTE Band

Sammanfattning: The planar dual band monopole antenna is presented in this project report for Long Term Evolution (LTE). The proposed planar monopole antenna is selected because of its simple structure, cost effective components and excellent performance. The antenna operates in 3.4 GHz to 3.6 GHz and 3.6 GHz to 3.8 GHz in desired LTE frequency band. The frequency bands 3.4- 3.6 GHz and 3.6- 3.8 GHz are already available as a study of current plan according to UMTS and LTE   systems.   The designed antenna works parallel with the LTE radio access; packet core networks are also involved. A very well developed and good designed antenna relaxes the other system components and improves the performances of the whole system. For the portable application and for the multiband scenario, planar monopole is the best candidate for the proposed two bands. LTE (3.4 GHz-3.6 GHz) and LTE-Advanced (3.6 GHz-3.8 GHz) antennas are designed for portable wireless devices. Radiation pattern and operating frequency are varied according to feeding of antenna.  Return loss, radiation pattern, antenna efficiency, bandwidth and gain are important parameters of the designed antenna and are measured after simulation through CST Microwave Studio. The designed antenna is then fabricated in KTH antenna Lab.
