However, creating directional antennas allowed more stations to share channels and that’s the subject of a recent post by [John Schneider]. When it comes to antennas, ham radio operators often ...

One of the main benefits of directional antennas is that they can focus the signal strength and reduce the interference from other sources. This can improve the quality and reliability of the ...

When you think of directional ham radio antennas, you probably think of a Yagi, cubical quad, or a log-periodic antenna. These antennas usually are in a horizontal configuration up on a high tower.

Abstract: This chapter discusses different techniques to realize low‐cost beam‐reconfigur‐able and multi‐beam directional antennas. Generally speaking, the cost of beam‐reconfigurable high‐directivity ...

Directional antennas are designed to propagate radio waves in a specific direction with a high concentration of focus. These are excellent for direct communication between two points. In reality, no ...

Imagine taking the radio frequency properties of the dish antennas you see on rooftops and knitting them into a wearable ...

Reconfigurable intelligent surfaces (RIS) will be an important technology pillar of the next 6G mobile communications ...

Abstract: In this paper, we examine a number of issues relating to the inter-HAP handoff process for broadband communications that operate with fixed or steerable directional antennas, allowing a ...
