Miniaturization of Microstrip Antennas for Applications in 4G Technology

摘要

This paper presents a new proposal of microstrip planar antennas designed for frequencies of 2.5 GHz and 700 MHz, with an improvement in bandwidth and miniaturization. Using the truncated ground plane, it is achieved a reduction of about 70% in size in both antennas. The antenna designed for 2.5 GHz has the bandwidth changed of 55 MHz for 580 MHz, whereas the antenna designed for 700 MHz, the change was of 20 MHz for 268 MHz.
