Book Description
This book provides practical and theoretical aspects for automotive antenna measurements. It comprehensively covers all the information you need to design, develop, place, and use antennas and antenna systems in automotive applications. Special chapters are devoted to some of the most advanced topics in this area, including OTA measurements for Vehicle to Everything (V2X) applications, emulation of virtual drive testing, and specific topics for measurements of automotive RADAR systems. You will understand the various measurement techniques specifically for automotive antennas, including chamber design, absorbers, near-to-far field transformation, and some of the newest techniques such as the use of drones. The book presents both well accepted and standard practices and includes innovative methods that help you quickly adapt to the rapidly evolving field of automotive antenna testing today. This is an excellent reference for antenna engineers, automotive system designers, and anyone who measures and designs antennas for automotive applications.

Book Description
The purpose of the third AFCRL Trailblazer II reentry vehicle flight was to study the effects of shock ionized air on the performance of a microwave antenna system located in the expansion region of the nose cone. The system consisted of a pair of cavity-backed circumferential slot antennas mounted one behind the other on the conical afterbody of the reentry vehicle. During reentry, measurements of antenna impedance mismatch, interantenna coupling, signal attenuation and antenna pattern distortion were made. The data have been compared with computed values and found to be in good agreement. This experiment thus establishes the validity of the various microwave and flow field models and calculations used to obtain the theoretical values in the shoulder region of the reentry body. These results will now serve as a standard against which to compare the properties of various chemical alleviants which are being studied in other flights. (Author).

Book Description
This paper describes comparisons of analysis and measurements of antenna patterns on automobiles in the VHF and UHF frequency bands. The actual measurements and analysis were performed at six different frequencies ranging from 41 MHz to 918 MHz. An antenna on a vehicle in a roadway environment in the presence of Earth does not have antenna patterns or input impedances as if it were located in free space or over a perfectly conducting ground plane. Antenna patterns of a whip antenna on a vehicle were measured on an outdoor antenna range with the vehicle on a 10 meter diameter turntable. Patterns were also measured with the vehicle over real ground away from the turntable to determine the effects of the steel turntable on antenna patterns. The three-antenna gain measurement technique was used to measure antenna gain. The measured patterns and gains were compared to predictions using the Numerical Electromagnetics Code (NEC-4).

Book Description
Describes the VHF and UHF antennas for the 30-3000 Mhz range that have been developed over the past 50 years, including many designs that have not previously been treated in detail, and several new uses for old designs. Among the topics are methods of predicting and measuring the performance of antennas, and how it is affected by the local environment, both normal and adverse, and by the structures on which the antennas are mounted, both fixed and mobile (including humans). Addressed primarily to practicing antenna engineers; the basic theory is assumed to be known except for the less known types. Distributed by INSPEC.
