A mobile computing device antenna according to one example includes a folded monopole element, a ground plane coupled to the folded monopole element by an antenna feed, a parasitic element that couples the folded monopole element to the ground plane, and a metal frame that encompasses the folded...
1.A system comprising:a support structure;a larger ground plane mounted to the support structure; andan antenna module that is positioned above the larger, mounted ground plane,wherein the antenna module includes an antenna and a separate, smaller ground plane that is smaller than the mounted gr...
Numerical optimization has been ubiquitous in antenna design for over a decade or so. It is indispensable in handling of multiple geometry/material parameters, performance goals, and constraints. It is also challenging as it incurs significant CPU expens
Satellite antennas concentrate the satellite's transmitting power into a designated geographical region on earth and avoid interference from undesired signals transmitted from outside of the service area. The antenna radiation characteristic is usually specified by its half-power beamwidth (HPBW). For an...
This paper presents a solution to this problem, introducing a dual antenna diversity scheme for the 2.4GHz ISM band and its beam selector circuit for controlling the diversity scheme. The proposed antenna produces an omnidirectional pattern and two directional patterns with very large nulls in their...

The change in dimension of the antenna design and its impact on antenna performance is examined through a parametric analysis. This segment depicts a detailed antenna structure analysis to attain UWB and dual-band notch frequency features. First, to achieve the UWB frequency spectrum, the ground pl...
Synthesis comply that substrate is an essential factor in the micro strip antenna, which provides physical support and strength to the antenna along with flexibility. As the antenna needs to install on the vehicle, the substrate selection must be made on its conformal nature, which can install ...
