Antenna Basics
 
By Rohde & Schwarz

This white paper describes the basic functionality of antennas. Starting with Hertz's antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained.

Antenna Location Is Not An Architectural Decision
By Alfred T. Yerger II, Bird Technologies

There are many different types of antenna systems and interference problems such as intermodulation, receiver desensitization, transmitter noise, or adjacent channel interference. However, one of the many recurring problems is in the location of the antenna.

SENCITY Shield Antennas Presentation

The SENCITY Shield antenna platform operates in frequencies ranging from 380 to 6000 MHz and has high power capabilities up to 100 W and more. It features high RF power handling, small form factors, low visibility, and uniform signal distribution. 

Developing Efficient Design Procedures For Wideband, Low-Profile Antennas Using Altair FEKO

Traditional analytical propagation models are not applicable to short-distance near-ground signal propagation, so numerical modeling is required. FEKO EM simulation technology offers superior effect capabilities that account for mutual coupling between receiving and transmitting antennas.

The Strange Case Of Dr. Modeling And Mr. Simulation

Simulation cannot necessarily provide performance data when the equipment is designed for use on a satellite or something else. Modeling tools can synthesize an equivalent antenna model using its design specifications as input data, so its position and performance can be analyzed while on a platform.

Antennas For Tactical Communications

This brochure provides an overview of Cobham’s Link16, MIDS, JTRS, and JTIDS tactical communications antennas. These antennas have been used in ground-to-air terrestrial, naval, and airborne communications applications with great success.

How To Measure All Types Of Antennas Using Very-Near-Field Measurement
By Ruska Patton and Ning Yang, EMScan

In order to help avoid sending antennas that fail to meet specified design criteria, regulatory requirements, or consumer satisfaction to the marketplace, designers need to characterize the antenna to meet all of the performance criteria. 

The Basics Of Quadrifilar Helix Antennas
By Bill Slade, Orban Microwave

The ability to receive or transmit a tight beam of circularly polarized radiation while minimizing unwanted radiation is imperative to good communication. For such applications, the axial-mode quadrifilar helical antenna provides high performance and a robust platform, both in space and on the ground.  

Directional Couplers Brochure

Dielectric Labs Inc. (DLI) introduces a series of surface-mount directional couplers that span the C-, X-, and Ku-band frequency spectrums, and are available with 10 dB and 20 dB coupling values, and a common footprint for maximum flexibility.
