Embodiment Construction

[0027] The specific implementation mode that the present invention adopts is described in detail below in conjunction with accompanying drawing:

[0028] In order to overcome the shortcomings of the prior art, the present invention adopts a new realization structure. Such as figure 1 The basic structure of the patch antenna shown and figure 2 The structure of the solar cell is shown, and it is found that they have a similar structure: the top electrode or patch antenna unit is made of metal or other conductors, and the antenna base or solar cell semiconductor base is in the middle, where the solar cell semiconductor base usually includes an N-type semiconductor region and P-type semiconductor region, and form a PN junction. The bottom is ground plane. The solar cell-based patch antenna integration can be realized by using the semiconductor substrate of the solar cell as the substrate of the antenna. The semiconductor material characteristics of the existing commonly used ...

Abstract

The invention provides a patch antenna-integrating device of a solar battery, which is specifically characterized by using a part of the solar battery as a substrate for a patch antenna. A patch antenna unit, which is separated from a top electrode of the solar battery, can be designed individually. The solar battery and the patch antenna share the ground plane. Or, the top electrode of the solarbattery is used as the ground plane for the patch antenna. According to the invention, the volume of the integrating device can be reduced and the design limit can be lessened.

Description

technical field [0001] The present invention relates to the fields of patch antenna or Microstrip antenna (patch antenna or Microstrip antenna) and solar cells, specifically, the present invention realizes a device for integrating patch antennas and solar cells. Background technique [0002] Wireless communication uses the transmission of electromagnetic waves in space to realize communication. In wireless communication, antennas are used to radiate and receive electromagnetic waves into space. In recent years, the application of wireless communication has become more and more extensive, such as GSM, WLAN and so on. With the development of the Internet of Things, the application of global positioning (GPS), ZIGBEE, radio frequency tag (RFID) and other technologies will become more popular. These applications hope that the equipment will be miniaturized and cost-effective, and the antenna design is the key factor to achieve miniaturization and cost reduction. For example, th...
