الملخص الإنجليزي

Multiple input multiple output (MIMO) technology is one of the key techniques used in the next generation Wireless Communication, MIMO can either increase the transmission systems reliability by applying diversity or increase the achievable data rate by transmitting several spatially separated data streams in parallel.

This thesis presents an implementation and performance evaluation of multiple antenna system using a compact folded loop antenna (FLA) covering LTE2600/WIMAX3.5/WLAN2.4/5.2 frequency bands for handheld devices.

First of all, a single element compact internal penta-band FLA is proposed on a ground plane of size equivalent to a handheld device.

Parametric analysis study has been performed to get the required specifications and simulated results exhibit that for all the bands the proposed FLA features have nearly good omnidirectional radiation patterns with proper gain.

Next an implementation of MIMO configuration of the FLA was then studied.

The MIMO antenna also designed to be suitable to a handheld devices form factor.

The goal is to design a two element multiple antenna on the same ground plane with lower correlation values while keeping same operating bands and gain.

Three different cases with different configurations of the two antenna placement on the ground plane has been designed to compare the results in terms of return loss, mutual coupling and correlation.

The design and optimizing of the performance of the proposed antenna are performed by using a high frequency structure simulator HFSS.

The result meet all the required specification where the proposed design results maintaining a value of correlation coefficient below 0.5 over the frequency bands of operation and nearly 10 dB diversity gain are obtained
