The quadrifilar helix antenna (QHA) has emerged as a versatile solution for modern communication systems requiring compact form factors, wide angular coverage and stable circular polarisation.

Receiving a signal from a geosynchronous satellite 22,300 miles out or a GPS satellite over 10,000 miles away is a challenge. Big gain antennas usually are necessary. But that’s just the opposite of ...

Amateur radio operators like to say that working a contact in space can be done with a simple handheld transceiver and a homemade antenna. And while that’s true, it’s true only for low Earth orbit ...

Maxtena Inc. has introduced an advanced, tiny, patented GNSS antenna for high precision and autonomous multi-frequency applications. The M9HCT-A-SMA antenna is a high accuracy, multi-frequency active ...

As the space industry evolves its focus from large satellites to smaller ones with the same functionality, there is a growing need for the hardware on board to shrink as well. A group of mechanical ...

When an earthquake, flood, or other disaster strikes a region, existing communication infrastructure such as cell phone and radio towers are often damaged or destroyed. Restoring emergency ...

No audio available for this content. While often an underestimated component of a positioning and navigation system, a GNSS antenna is critical to a receiver’s success in acquiring all available GNSS ...

This 4-part report discusses antenna fundamentals and the various types of antennas used for short range devices. Fundamentals are presented along with practical design principals. It is excerpted ...
