This paper introduces the specification and performance analysis of broad frequency range antenna for 5 G mobile phones. The suggested antenna functions at the frequency spectrum of 28 GHz and its configuration are permanently matched over very high frequency bands, including 4.25 GHz, 7.055 GHz, 12.48 GHz and 15.26 GHz, as well as for the reallocation of the expanded 5 G spectrum of communications. Mobile terminals are compliant with the antenna that is being built.

Voltage Conversion

Conventional line frequency transformers have the disadvantages of large volume and low efficiency. The medium or high frequency transformers based on power converters can achieve high power conversion with small footprint have drawn popularity in numerous industrial applications. Unregulated resonant converters, LLC and CLLC resonant converters, with fixed voltage conversion ratio operating at resonant frequency, which are also known as DC transformers (DCXs), are attractive owning to their high efficiency characteristic. Nevertheless, there are issues associated with DCXs in real applications. Regulation capability and automatic resonant frequency tracking capability are the two most important issues for DCXs. The main work of this paper is to characterize the resonant converters based DCXs, and overview the issues and solutions associated with DCXs. Guidelines can be provided for researchers and engineers when designing the resonant converters based DCXs.
