摘要
A seven-band antenna for vehicle-mounted T-BOX with a compact structure is proposed and studied. The proposed antenna is composed of a monopole branch and a ground branch. In addition, a slot is embedded in the monopole branch for bandwidth enhancement. By using 0.25- and 0.5-wavelength modes, the lower band (824–960 MHz) and higher band (1710-2690 MHz) are covered. The working mechanism is analyzed based on S-parameters and surface current distributions. The attractive merits of the proposed antenna are that the structure is compact with a small ground, and no lumped element is used. The measured results show that the antenna can cover the lower band of GSM850/900 and the desired upper band of DCS1800/PCS1900/UMTS2100/LTE2300/2500. The measured efficiencies are also presented. © 2018, Electromagnetics Academy. All right reserved.
