Good antenna measurements don’t just happen

https://www.antenna-theory.com/measurements/antenna.php

Today’s class covers the topic of antenna measurement, which is essential in antenna design verification process. There are a  number of techniques such as near field and far field. Measurement equipment for a typical antenna measurement setup are network analyzer, signal generator, positioner (turn table) and spectrum analyzer.

A good measuring setup presents minimal discrepancies between the measured and simulated results.

Today’s class discusses the topic of antenna array – a very interesting subject in Antenna Design.

Arrays are adopted for communication devices that requires high precision, highly directive coverage. Similar to the radar operation, array antennas allows beam steering as well as interference nulling.

A discussion with one of my PhD students who is currently doing a research on composite material for microstrip antenna.

Learning Outcomes

1. Students are able to describe the operating mechanism of the antenna
2. Students are able to design and evaluate APERTURE antennas to meet application requirements

Types of antenna considered in this topic is

1. Horn Antenna
2. Parabolic Antenna
