Design and Optimisation of an LTE Mobile Phone Antenna

An LTE antenna is designed for use in a mobile phone, using a dual-port configuration. The antenna is also optimised for minimal reflection coefficient at both ports and cross-coupling between the ports as low as possible. 4G/LTE provides a comprehensive and secure all-IP based mobile broadband solution to all kinds of mobile communication devices.  WiMAX, HSPA+ and first-release Long Term Evolution (LTE) have been the dominant technologies in this market.  These technologies have been designed for channel bandwidths of 5 to 20 MHz (optionally up to 40 MHz) and offer peak data rates of ~ 100 MBit/S for high mobility devices and 1 GBit/s for low mobility devices.
