Abstract
We propose a new small multiband printed antenna for wireless telecommunications modules that actualizes Machine-to-Machine applications. The proposed antenna is based on our previous design comprising symmetrically arranged trapezoidal elements and rectangle strip elements. It achieves operation in quad-bands: 700 MHz, 800 MHz, 900 MHz, and 2 GHz. In the new antenna, we add new folded strip elements to cover the GSM 1800 (DCS 1800), GSM 1900 (PCS 1850), W-CDMA (Bands I, II, IV, and V), and LTE (Band 1) bands. The new antenna achieves operation in multiple bands including LTE (Band 28), GSM 900 (E-GSM 900), W-CDMA (Band VI), GSM 1800 (DCS 1800), GSM 1900 (PCS 1850), W-CDMA (Bands I, II, IV, and V), and LTE (Band 1). Frequency characteristics are analyzed using a simulator based on the method of moments, and the validity of the numerical results is shown based on measured Voltage Standing Wave Ratio characteristics of the prototype antenna.
