Multiband microstrip patch antenna for LTE application

Abstract

This paper presents a multiband patch antenna for LTE application. Conventional single band antenna only operates at one specific frequency and will require multiple single band antenna to support multiband application. Consequently, the antennas will consume more space in the microwave circuitry. The propose antenna is designed to operate at multiple LTE frequencies, which are 1.8 GHz, 2.1 GHz, and 2.6 GHz. The simulation will be done using Computer Simulation Technology (CST) Microwave Studio software and will be fabricated for further development. The simulated reflection coefficient (S11) results for the proposed design are -14 dB, -23 dB and -18 dB while the measurement results are -13 dB, -16 dB and -16 dB. Both results are simulated and measured at 1.8 GHz, 2.1 GHz, and 2.6 GHz respectively.
