A printed reflectarray is a high-gain, low profile, low-cost antenna that combines the advantages of parabolic reflector antennas with microstrip arrays. This white paper demonstrates how to easily create a printed reflectarray and its simpler feeds through the use of FEKO simulation software.
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.
What makes communication so challenging in an airport is its large coverage area and high-capacity requirements. That’s the challenge YYC Calgary International Airport faced when it built its new international terminal. The airport had virtually no commercial or public safety coverage from the macro and, as a result, the new international terminal faced both coverage and capacity issues.
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.
