Characteristic Mode Analysis of a Metallic Ring Antenna

Characteristic mode analysis is carried out to give insight into the radiation properties of a metallic ring antenna. The normalised surface current distributions and far field patterns of the first four eigencurrents of a metallic ring antenna based on the … Read More

Automotive Windscreen Antenna Analysis

Introduction Vehicle manufacturers are incorporating an increasingly wide variety of antennas into vehicles for AM, FM, television and GPS reception, for GSM communication, for automated tolling, and so forth. To find a combination of antenna topologies and locations, which is … Read More

Impedance Loaded Omni-Directional Left-Handed Loop Antenna

An omni-directional left-handed loop antenna was proposed by Iizuka and Hall in [1].  The antenna consists of wires and LC lumped elements to load the wires appropriately.  Figure 1 shows the geometry of this antenna. The loop antenna was simulatd … Read More

Edge-Fed Rectangular Microstrip Patch Antenna

An example of how a rectangular microstrip patch may be fed at an edge. This example models the rectangular microstrip patch antenna that was analysed by Wu et al [1].  It consists of a simple rectangular microstrip antenna with the reference plane … Read More

Antenna Placement on Aircraft Platforms with FEKO and Antenna Magus

A dielectric patch antenna is designed to user specification with Antenna Magus and placed on an aircraft for simulation of various performance parameters with FEKO. System integrators are often interested in the effects on performance of an antenna when it … Read More

Waveguide Transition Modelled in FEKO and FEST3D

A rectangular to circular waveguide transition is modelled in FEKO and FEST3D. The interface between FEKO and FEST3D allows the usage of FEST3D results (the modes calculated at one of the ports of the FEST3D model) as excitation for the … Read More

Bluetooth Integration in a Vehicle

This white paper uses Antenna Magus to design a suitable antenna for a bluetooth tranceiver in an automotive application and investigates whether the antenna will function properly in the vehicle environment. It has become commonplace for vehicle manufacturers to integrate … Read More
