Multiband antennas

5G antenna is so compact size but has to get large bandwidth, high gain and good radiation efficiency to be able to support huge data rate for 4.0 revolution industry. In this paper, a novel 4x4 multiband Multiple Input Multiple Output (MIMO) antenna is designed. Using the semi-circle structure, the proposed antenna not only achieves wide band but also is easy to optimize operate frequencies at millimeter wave band.

The Topic of microstrip antennas is an old subject that started over 40 years ago. Microstrip antennas are low profile and easily fabricated. This subject has passed through several stages that make it survive tell now and still in continues progress. The main stage is the development of low loss low cost dielectric materials that make it possible to design an effi‐ cient low profile microstrip patches. The stage of developing analysis methods and models that helped in the design of radiating...

Antenna Segment Tradeoffs The antenna segment establishes the available RF bands. Although much research has been applied toward creating an “all-band” antenna, multiband radios generally require at least one antenna per decade of RF band (e.g., HF, VHF, UHF, SHF, etc.). In addition, the antenna determines the directional properties of the receiving system. Sectorized antennas, static beamforming arrays, and adaptive beamforming arrays (smart antennas) each have different spatial and temporal properties, the most significant of which is the pattern of transmit and/or receive gain....
