Ground plane effect on a antenna

WebMay 21, 2024 · Don't forget, the ground is the other half of your antenna with a monopole. Adding radials replaces that effect to a great degree (they are a compromise - still not as effective). But as pointed out, the XMIT/RCV aspect is a "two way street". So, in almost every case, this old axiom applies: "If you can't hear 'em, you can't work 'em". WebApr 12, 2024 · An antenna with a quasi-balanced feed is fabricated at f0 = 3 GHz using a ground plane of 5 λ 0 × 5 λ 0, which is empirically known to give an adequate approximation of the infinite ground plane. The fabricated antenna's photographs are shown in Figure 10. The small circles and dots in Figures 8 and 9 are the experimental …

The … WebJan 1, 2011 · Therefore, the ground plane width must also have significant effect on the antenna performance. The prototype antennas with varied ground plane width from 25mm to 40mm are simulated and their return losses are plotted in Figure 3.

WebJul 1, 2015 · It has been shown that the ground plane has significant effects on antenna properties such as impedance bandwidth, radiation patterns, gain and time-domain response [ 7 - 10 ]. WebThe antennas were assumed to be mounted on the ground, which, generally, is not a perfect electric conductor (PEC) since its usual conductivity does not exceed mho/m. However, since the radiation characteristics of an antenna depend on the ground conductivity, it is convenient to “create” an artificial PEC ground.

WebA quarter wave monopole mounted against a perfect ground will have an impedance of around 36Ω but by bending the radials down at an angle of 45°, we increase this to around 50Ω whilst at the same time lowering the radiation angle more towards the horizon. (42° is the theoretical perfect angle for 50Ω feed, but who’s measuring!) http://www.astrosurf.com/luxorion/qsl-radials.htm
