Multiband microstrip antenna array with slot and array method for GSM, WCDMA, and LTE

摘要

The development of communication technology is increasingly fast and diverse. Some of these technologies include Global System of Mobile Communication (GSM) which has working frequency at 900 MHz, Wideband Code Division Multiple Access (WCDMA) has working frequency at 1.8 GHz, and Long Term Evolution (LTE) which has working frequency at 2600 MHz. To provide the needs of data access at high speed with various standards, a multiband antenna is designed which supports wireless communication. One type of antenna used for wireless communication is a microstrip antenna. As novelty, this research proposed a multiband microstrip antenna based on slot for GSM, WCDMA, and LTE. Array methods also was used to increase gain on microstrip antenna. The antenna is simulated using Advanced Design System 2009 (ADS 2009) software, and fabricated using FR4 substrate with ε_r= 4,3, tan δ = 0,0265, h = 1,66 mm, and measured using Vector Network Analyzer (VNA). The measurement results show the validation of the multiband antena design.
