Next generation wireless terminals and devices will include large amounts of antennas serving various proposes and standards. This will pose new size and volume constraints on such antennas and their accompanying radio-frequency front-ends (RF-FE). In addition, at higher frequency bands (i.e. millimeter waves), beam-forming (or beam-switching) will be required to provide reliable communication links and avoid constant blockage from nearby obstacles. Traditionally, antennas are designed and optimized to be interfaced to their RF-FE via a 50Ω input impedance. Circuit and antenna designers were always asked to satisfy this requirement to have a good matching over the band of interest. This scheme does not always provide the best overall system performance. Active antennas can provide better gain, bandwidth and efficiencies if properly designed.
This talk will start with the historical developments of active integrated antennas, their features, importance, applications and design procedures supported with examples from literature. Basic definitions and design aspects will be highlighted for the design of active integrated antennas. Then, it will highlight a new co-design methodology that my group has come up with to co-design active and passive parts simultaneously without the requirement of 50 ohm. This method has been proven very efficient as compared to other conventional methods and relaxes the separate requirements of 50 ohm matching. Examples of this co-design method will be given for narrow-band, wide-band and ultra-wide band-based active integrated antenna designs.
