Tough technical requirements are being put on handsets. Mobile phones have to deal with an ever increasing number of services, while at the same time the cost of the systems is being reduced. RD in the mobile phone industry copes with this situation by continuously improving the mobile phone efficiency in order to be able to comply with the grade of service in the mobile network. Thus, we are moving towards mobile designs, which are not only becoming thinner, smaller and more complex with every generation but also have to perform with the same or even better performance, and at more frequency bands. In addition to maximizing the antenna-accepted power of the handsets, the effects on the antenna performance from surrounding objects such as the human body have to be studied and considered. Homogeneous models are used when measuring the effects on antenna performance and represent a conservative estimation of the antenna losses and dissipated power. The performance of the antenna and the entire system may be quantified using sets of technical requirements for both passive and active modes. In passive mode the antenna performance is often measured by the antenna efficiency, which is subdivided into the radiation efficiency and the return-loss efficiency. In active mode the entire system efficiency is defined by the Total Radiated Power (TRP) on transmitting (Tx), and the Total Isotropic Sensitivity (TIS) on receiving (Rx). The active performance of the handset is often measured using exact and time consuming procedures. These have to be conducted several times during the development phase of the device. Furthermore, the product has to be developed to a certain stage before any measurement or reliable prediction of antenna performance is possible. The results of simulation for the several system complexity levels and its comparison to measurements are compared for the Sony Ericsson M600 mobile phone. All measurements were cond[...]
