How to build performing antennas for LoRa, WiFi, 433MHz, Airplanes etc.(NanoVNA, MMANA-GAL)
By Andreas Spiess | Author Youtube Channel | 7 de jan. de 2021
I am often asked: Where do I get a good antenna? Or: Is this a good antenna? Unfortunately, you do not see if an antenna is good or bad before you do some measurements. Or you build one yourself. That is what we will do today. Be it for satellite reception, for LoRa, weather balloons, or even for Wi-Fi. Like that, we know what we have. And even can save some money.
Antenna Tutorial incl. cheap DIY Antenna Tester (LoRa, ESP32)
By Andreas Spiess | Author Youtube Channel | 11 de mar. de 2018
Everything goes wireless these days. This is why we have a close look at the “black magic” of antennas, how they work, what is essential, and how to test them. Based on this knowledge we will build a cheap antenna tester for LoRa antennas. A similar device can be built to test Wi-Fi antennas. It uses an ESP32 TTGO board on one side and a Wemos D1 mini with a Hope RFM95 module on the other side.
How to Design a PCB Antenna for 2.4GHz
By Debashis Das | https://circuitdigest.com/ | May 27, 2020
Antennas are everywhere these days, most of the mainstream technologies like smartphones, security, and IoT devices use antennas to communicate between them and that's why RF becomes one of the most fascinating and robust corners of engineering and design. So, the author´s goal is to give readers some of the basic ideas about what an antenna is, how it works & how to build your 2.4 GHz antenna.
Miniaturized Printed Inverted-F Antenna for Internet of Things: A Design on PCB with a Meandering Line and Shorting Strip
By Cheuk Yin Cheung, Joseph S. M. Yuen, Steve W. Y. Mung | International Journal of Antennas and Propagation | First published: 26 March 2018
This paper focuses on a printed inverted-F antenna (PIFA) with meandering line and meandering shorting strip under 2.4 GHz industrial, scientific, and medical (ISM) band for Internet of things (IoT) applications. Bluetooth Low Energy (BLE) technology is one of potential platforms and technologies for IoT applications under ISM band. Printed circuit board (PCB) antenna commonly used in commercial and medical applications because of its small size, low profile, and low cost compared to low temperature cofired ceramic (LTCC) technology. The proposed structure of PIFA is implemented on PCB to gain all these advantages. Replacing conventional PCB line in PIFA by the meandering line and meandering shorting strip improves the efficiency of the PIFA as well as the bandwidth. As a case study, design and measurement results of the proposed PIFA are presented.

Book - Introduction to Multiple Antenna Communications and Reconfigurable Surfaces
By Emil Björnson, KTH Royal Institute of Technology, Sweden, emilbjo@kth.se and Özlem Tuğfe Demir, KTH Royal Institute of Technology, Sweden | Publication Date: 17 Jan 2024
This book gives a gentle introduction to multiple antenna communications with a focus on system modeling, channel capacity theory, algorithms, and practical implications. The basics of wireless localization, radar sensing, and controllable reflection through reconfigurable surfaces are also covered. The goal is to provide the reader with a solid understanding of this transformative technology that changes how wireless networks are designed and operated, today and in the future.

Line Loss and Coax Cable Loss / Antenna Gain Calculator
By Juan Carlos | CO8TW WEB site.
Here's a quick line loss calculator to use Note that the simple program used for this web page gives a very close approximation for additional losses due to SWR. This program is provided "as-is". It is thought to be accurate but it is the responsibility of the user to verify the accuracy of the calculations when using this program.
