ground plane

[′grau̇nd ‚plān]
(electricity)
A grounding plate, aboveground counterpoise, or arrangement of buried radial wires required with a ground-mounted antenna that depends on the earth as the return path for radiated radio-frequency energy.

The Performance Margin is defined in terms of accelerations in the Ground Plane in physically meaningful and intuitive units of acceleration relative to the acceleration due to earth's gravity.
The UWB MIMO antenna in [18] could achieve a mutual coupling larger than 20 dB in the entire operating band by etching a T-shaped slot as well as a narrow slot on the ground plane. In [12], a miniaturized MIMO antenna has been proposed for industrial applications, which had a novel decoupling stub structure etched in the ground plane to improve isolation between the antenna elements over the complete frequency band.
The ground plane plays a vital role in improving the electrical performance of an antenna as it improves the antenna element gain [17-18] and directivity (~7-9dB) [18], increases the front-to-back ratio (FTBR) [18], reduces the electrical size of an antenna [19], and can be used to tune the antenna resonant frequency [19].
The lobbies are connected to the ground plane with a distinctive water features that flows from the inside to the outside creating a calming sound for the public, it stated.
As shown in Figure 11, parasitic capacitances, [C.sub.ca_c] and [C.sub.ag_c], existed between the controller and the antenna, and between the antenna and the ground plane, respectively.
based on this we will compare whether replacing the ground plane with single and double layered metamaterial enhances its return loss and band width or not.
Therefore, the technique used in this paper to obtain triband PIFA antenna is by combining the use of slots on the ground plane and the particle swarm optimization (PSO).
The T-shaped feedline is completely covered by the ground plane on the other side of the PCB.
In this paper, the UTD method is utilized to calculate the farzone amplitude patterns in the E and H planes, and to examine the impact of the square and circular ground plane edges on the amplitude patterns of a conical horn, and rectangular and circular waveguide antennas.
