Integrated of an SIW hybrid ring coupler, a Yagi monopulse antenna is designed. Measured gain of the sum pattern is higher than 13 dBi, whereas the maximum null depth of the difference pattern is ...

The antennas can be stowed within a one-unit cubesat, which measures 10 centimeters on a side. When deployed, the antenna operates from the 156.5 megahertz to 162.5 megahertz band.

A multisector antenna divides its surrounding 360-degree space into multiple areas (sectors) for transmitting and receiving radio waves simultaneously and independently in each sector. The antenna ...

The design, prototyping, and testing of a multidirectional, closely spaced Yagi antenna is described. A driver is surrounded by eight directors. The directional radiation pattern is reconfigured using ...

Figure 9: The irradiation of the antenna in the 3D space The last two figures clearly indicate a directional behavior of the Yagi antenna in a particular direction. Yagi antenna design In this section ...

These highly directional antennas have a driven element and a number of parasitic elements, specifically a reflector behind the driven element and one or more directors in front of it.

Greetings one and all..... Some great reference material on this forum, and I am hoping some answers / guidance to my situation / query below. Background I live in County Down, Northern Ireland, about ...
