Wideband antenna

Abstract

A wideband / broadband antenna is described, comprising a dielectric substrate with a first surface with an antenna feed with two conductors, comprising a first feed connection and a second feed connection, wherein the second feed connection is or acts as the ground. A first conductive layer extends from the antenna feed in a first direction and is electrically connected to the first feed connection, wherein the first conductive layer extends in a direction away from the antenna feed, and to a first end edge. A second conductive layer extends in a second direction, away from the first conductivelayer, and is electrically connected to the second feed connection. A non- conductive zone separates the first and second conductive layers. On a second surface of the substrate there is a third conductive layer which extends from a second end edge in the direction towards the antenna feed, the extent of which at least in part coincides with that of the first conducting layer at the first surface. The first end edge of the first conducting layer and the second end edge of the third conducting layer substantially coincides, and the first and third electrical layers are electrically connected with each other at or near said end edges. Apart from said electrical interconnection at the edges, the layers are electrically separated from each other.

Description

technical field [0001] The invention relates to a broadband / wideband omnidirectional antenna. Background technique [0002] There is an increasing need for omnidirectional broadband / broadband antennas. More and more appliances and devices are now connected to wireless networks, and with the development trend of the "Internet of Things" (IoT), everyday items such as household appliances, clothing, accessories, machines, vehicles, buildings, etc. are now more frequently equipped with Wireless connections. This enables the device to receive commands from users and other entities in order to be able to be controlled remotely, relay information from sensors, etc. Providing a good antenna for this type of use remains the main issue. From the perspective of radiation and communication, antennas are usually placed in bad positions when they are applied to devices such as household appliances. The locations where the antennas that will communicate with the device are placed are o...
