With the increasing demand for ubiquitous multimedia services, next generation cellular systems are expected to provide higher data rates and robustness to the changing wireless environment. As a fundamental part of any cellular system, an antenna plays a primary role and its performance is directly related to the quality of communication signal. However, the overall system performance is determined by the total performance of each component, such as antenna and baseband units. Therefore, it is critical to consider overall system design to satisfy the increasing demand for next generation cellular systems. To this end, the antenna not only requires high-gain and high-efficiency antenna elements, but also operates effectively as an antenna system together with the baseband signal processing. Thus, in this special issue, we are seeking novel contributions to antenna design and system technologies for next generation cellular systems. Both “antenna design” and “antenna system” as well as their joint design are of interest. Potential topics include, but are not limited to:

• Transmit and receive subset antenna selection in MIMO systems
• Limited feedback communication for localized and distributed MIMO systems
• Impairment modeling and mitigation techniques
• Channel estimation and robust system engineering in the presence of channel estimation errors
• Joint relay-and-antenna selection in multiantenna communications
• Multiantenna signal processing
• Adaptive and smart antennas
• Multiple antenna OFDM systems
• Channel characterization and modeling
• Indoor, urban, and terrestrial propagation
• MIMO antennas
• Multiband/wideband antennas
• Reconfigurable antennas and arrays
• Metamaterial antennas
