Metamaterial filtenna at 2.4GHz for bluetooth application

Abstract

Nowadays, modern technologies such as aerospace, medical electronics and communication systems requires reliability and accuracy to support a very large number of standards such as Bluetooth. Thus, there is a huge demand to have a bluetooth antenna that are both capable to have precise measurement and high reliability. Combination of filter and antenna or filtenna is an alternative solution in the RF frontend circuit to reduce the transmission losses. In addition, Metamaterials are materials typically engineered with novel or artificial structures to produce electromagnetic properties that are impossible to retrieve in nature. Metamaterials offer many advantages in electromagnetic applications from microwave to optical range, especially for the radiated-wave devices. Thus, in this project, a metamaterial filtenna at 2.4GHz for bluetooth application has been proposed and designed. It combines SRR band pass filter with MELC resonator antenna. All of the simulations are done using Computer Simulation Technology full wave simulator software. Then, we compared the proposed filtenna performances with conventional filtenna. From the simulation results, it can be seen that metamaterial filtenna has better performances in terms of higher antenna gain (5.44dBi) and low return loss (22.2dB).
