Abstract
Abstract Millimeter wave (mmWave) bands attract large research interest as they can potentially lead to data rate of almost 10Gbits/sec and huge available bandwidth where as the microwave frequencies are limited to 1Gbits/s. This paper presents a comprehensive review of millimeter wave communications, frequency bands proposed by ITU, applications of mmWaves, advantages, limitations, challenges and research directions. Various antennas proposed by researchers for mmWave applications are described in detail. The described models are analyzed and compared with common antenna parameters. Applications like HD gaming, ultra high definition multimedia, security and surveillance demand for high data rates and more bandwidth. These all applications will drive mmWvaes technology to develop and offer wide bandwidths with high speed data.
