Abstract

In this letter, a novel miniaturized multilayer internally printed antenna combined with two FR4 materials for triple Long Term Evolution (LTE) band operation is proposed. The proposed antenna is designed using a capacitive feed structure and an orthogonal meander line at the top edge of a subsection of the complete structure with dimensions of only 14 × 15 × 3.2 mm³. This covers triple-band operation (LTE700, LTE2300, and LTE2500). The complete dimensions of the mobile device are 50 × 100 mm². The reflection coefficient is measured and used to demonstrate that the operation bandwidth is 42 MHz in LTE700 operation by a 3:1 VSWR. It is also suited to two full-band operations (LTE2300 and LTE2500) by using the definition of the -10-dB reflection coefficient in two higher modes of operation.
