This paper describes the effects of various quality variables on microwave antenna performance, and provides insight into the long-term consequences of using a low-cost/ poor-quality antenna. It demonstrates the effect of operators’ preference for low-cost antennas without considering the total cost of ownership, as well as possible ill effects on their quality of service.
Carrier aggregation (CA) enables mobile network operators worldwide to provide faster data, and allows mobile devices to communicate on multiple LTE bands simultaneously. This, however, creates the challenge of avoiding interference between the bands while keeping up good reception and battery life. Multiplexers are an excellent solution for CA combinations that use closely spaced bands since they provide isolation between and within bands, while allowing them to connect to the antenna at the same time. This white paper discusses the challenges of carrier aggregation, and the important benefits of using multiplexer solutions to solve them.
Radio-frequency identification (RFID) technology uses electromagnetic fields to automatically identify and track objects with tags containing electronically stored information. This application note discusses a new approach to optimizing RFID antennas for this technology with the use of the new NI AWR Software product AntSyn™ antenna synthesis and optimization technology. This method employs evolutionary algorithms (EAs) to explore the design space and automatically determine the best performance options. This application note features a new method used for optimizing radio-frequency identification (RFID) antennas and describes two examples of RFID antennas created using this technology.
In this work, a high-gain broadband printed Yagi directional antenna for applications in ISM bands (686 and 915 MHz) is presented. The proposed antenna was designed to be implemented in a wireless system, devoted to water and wastewater level and underground flow measurements.
