AI Technical Summary

Problems solved by technology

However, based on the formula of c=f×λ, when it is applied to a WiMAX system with an operating frequency band of 3.5GHz to 5GHz, since the frequency is greatly reduced, the wavelength is greatly increased, so the radome needs to be quite thick correspondingly, and the overall antenna volume increase
At the same time, the multi-layer metal grid acts on the far-field of the antenna radiation field, and the entire antenna structure becomes larger, which limits its practicability

Embodiment Construction

[0038] The present invention provides an antenna structure with a radome and a method for increasing the gain thereof. The dielectric material with a metal pattern is used, and the radome is placed in the near field of the radiation field of the antenna structure to concentrate the radiation emitted by the antenna structure. The beam diameter of the radiation beam is wide, which increases the gain of the antenna structure.

[0039] Please refer to FIG. 1 , which shows a schematic diagram of an antenna structure according to a preferred embodiment of the present invention. The antenna structure 100 includes a radiation element 110 and a radome 120 . The radiation component 110 includes a radiation body 111 , a dielectric component 112 and an antenna feed-in end 113 . The radiation body 111 is located on the dielectric component 112 and uses the antenna feed-in end 113 to feed signals. The radiation element 110 can be various types of antennas, and is not limited to a specific ...

Abstract

The invention is concerned with the aerial structure, includes the radiation groupware and the aerial cover. It is: the aerial cover is with at least one layer of dielectric material; the upper surface of the dielectric material is with several S-shape of metal pattern, the bottom surface is with several reverse S-shape metal patterns comparative to the S-shape metal pattern. The S-shape metal pattern and the comparative reverse S-shape metal pattern couples in order to send the radiation wave packet from the centralize radiation groupware.

Description

technical field [0001] The invention relates to an antenna structure with a radome and a method for increasing the gain thereof, in particular to an antenna structure with a radome with high gain and a simple structure and a method for increasing the gain thereof. Background technique [0002] In recent years, due to the rapid development of wireless communication technology, wireless local area network (Wireless LAN) or personal wireless network (Wireless PAN) has penetrated into offices or homes. However, wired networks such as digital subscriber lines (Digital Subscriber Line, DSL) etc. are still the main ones connecting wireless networks in series. In order to wirelessize the network between metropolises and build backbone network facilities between urban and rural areas at a lower cost, IEEE 802.16a Worldwide Interoperability for Microwave Access (WiMAX) was proposed. , its transmission speed is 70Mbps, which will be about 45 times faster than the 1.544 Mbps of the exi...
