Simple Printed Multiband Antenna With Novel Parasitic-Element Design for Multistandard Mobile Phone Applications

摘要

A simple printed multiband antenna with parasitic-element design for multi-standard handheld terminals in mobile communications is presented. The proposed antenna performs three resonance modes covering six bands of wireless standards, including GSM, GPS, DCS, PCS, UMTS, and LTE 2300/2500. In geometry, the antenna simply consists of two metal stubs. One is an L-shaped driven stub working as a feeder and an embedded transmission line. The other is a U-shaped parasitic stub working as a radiator. With fully printed and simple configuration, the proposed antenna design is cost effective in manufacturing and easy to optimize for different frequency bands. Parametric studies and the design rule are included. The antenna occupies an area of 18 $,times,$37 mm $^{2}$ on top of a system board. This communication covers the details of the antenna design, working principle, and the performances of simulation and measurement.
