AWR Publishes Application Notes on Antenna Design

Design of a Near Field Communication Antenna System app note

AWR recently published two two application notes about antenna design. The titles of the two papers are: Design of a Near Field Communication Antenna System and Design Flow for Base Station Antennas. The NFC application note describes a sample Rohde & Schwarz NFC design using Microwave Office/AXIEM. The base station antennas article describes how antennas designed in Antenna Magus can be exported as models to AWR’s Microwave Office/AXIEM software for analysis and integration with circuits and other system components.

Design of a Near Field Communication Antenna System

Near field communication (NFC) is being developed as a form of contactless communication between wireless devices like smartphones and tablets. This technology enables users to do things like swipe their devices at the checkout stand or wave them over another NFC-compatible device to share information instantly without complicated setups or physical connections. The antenna systems of these NFC-enabled devices are a critical component. In general, the successful design of NFC antenna systems operating at 13.56MHz requires electromagnetic (EM) simulation of both the polling and listening sides of the antenna system, as well as the incorporation of discrete elements (including nonlinear diode bridges that convert RF energy into DC signals). The typical analyses performed include RF matching as a function of polling/listening distance, detection of DC signal levels under various.

Design Flow for Base Station Antennas

Automated synthesis of microwave devices has been gaining in popularity in CAE applications over the past decade. Antenna Magus now brings this capability to the field of antenna design. Antenna Magus provides a structured catalog of antennas with concise documentation, robust design algorithms, and export models. The documentation is researched, structured, referenced, and maintained to ensure that documentation on each antenna is well suited to the task at hand. The design algorithms produce working parameter sets based on user-defined objectives almost instantly. Antennas designed in Antenna Magus can be exported as models to AWR’s Microwave Office/AXIEM software for analysis and integration with circuits and other system components. All models are fully parametric and can be optimized together with other project components. This truly integrates the design of the antenna into the overall design of the device and the system.
