Design of microstrip antenna for LTE (Long Term Evolution) 700 MHz applications

This paper discusses the design of microstrip antenna which is used in cellular communication application especially at LTE 700 MHz network. The antenna was printed using FR-4 substrate material with dielectric constant of □_r = 4.65 and thickness of h = 1.6 mm. The overall dimension of the antenna is 135 mm × 32 mm × 1.6 mm with 50 Ω impedance. This antenna operates between 697.6 MHz and 784.9 MHz for return loss of less than -10 dB. The simulation results suggest that the antenna gain ranges between 1.5 dBi and 2 dBi with omnidirectional radiation pattern.
