1. Rotman Lens Design And Simulation In Software

    Since its invention in the early 1960s, the Rotman Lens has proven itself to be a useful beamformer for designers of electronically scanned arrays. Inherent in its design is a true time delay phase shift capability that is independent of frequency and removes the need for costly phase shifters to steer a beam over wide angles. This article uses the developed software to design and analyze a microstrip Rotman Lens for the Ku band.

  4. Ten Cues That It’s Time To Look Into A Channel Modeler

    A question Remcom is often asked is, “How is Wireless InSite® different from our planning tools?” While every tool is a little different, the most important differences between Wireless InSite and planning tools emerge when users need to simulate 5G mmWave and MIMO systems. This white paper presents ten cues that your organization may need a channel modeling tool like Wireless InSite to supplement your network planning efforts.

  5. WiFi Performance In A House with Two Routers

    Wireless InSite’s Communication System Analyzer provides capabilities for assessing the performance of LTE, WiMAX, 802.11n, and 802.11ac systems. The following example investigates WiFi throughput coverage in a house provided by 802.11ac routers operating at 5 GHz using an 80 MHz bandwidth.

  6. Simulation Of Beamforming Using FD-MIMO For LTE-Advanced Pro In An Urban Small Cell

    In this presentation, Wireless InSite MIMO is used to demonstrate an efficient method for predicting detailed channel characteristics for an FD-MIMO scenario in downtown Boston.

  7. Electrostatic Discharge (ESD) Simulation And Prediction For RF Devices

    ESD testing requires the use of many hardware prototypes, which is time consuming and expensive.   The ability to simulate the ESD testing process and pinpoint locations in wireless devices susceptible to ESD damage would be extremely valuable and allow engineers to reduce the number of prototypes required to design products for minimal ESD damage.  This presentation introduces a multiphysics-based ESD capability in Remcom's XFdtd that analyzes ESD testing via computer simulation.  This will save companies time and money by allowing ESD protection to be optimized during the design phase, thus reducing the number of prototypes required to be built and tested.

  8. mmWave Ray-Tracing Simulation With Diffuse Scattering In An Office Environment

    This presentation by Remcom demonstrates the use of Wireless InSite in a mmWave ray-tracing simulation with diffuse scattering in an office environment.

  9. RCS of Hellfire Missile Using Remcom's Accelerated X3D Model

    Accurate calculation of RCS at millimeter wave frequencies requires sufficiently detailed geometric representation of the target and physical modeling techniques that capture the scattering effects of small facets.  Highly detailed facet models and traditional methods for calculating RCS at these frequencies can often result in very long run times.  Using Remcom’s X3D with Physical Optics (PO) and Method of Equivalent Currents (MEC) model for calculating RCS, accurate results can be achieved within reasonable run times.

  10. Configurable Array Antenna Simulation For Base Stations

    In this app note, a MIMO antenna is created and simulated to generate return loss, coupling, and gain patterns for several different configurations and operating modes of the device. The ability to form either omni-directional or focused beams is also demonstrated.
