Abstract

The invention relates to a broadband planar antenna, which comprises a metal cavity and a feed network, wherein a set surface of the metal cavity is provided with two or more intersecting slot pairs;each slot pair is used for generating circularly polarized waves of different frequency bands and comprises two slots which are mutually perpendicular and intersected; and the feed network is used forfeeding each slot. In the broadband planar antenna, circularly polarized waves of different frequency bands can be respectively generated through the slot pairs under the feeding action of the feed network. Therefore, the broadband planar antenna does not need to adopt a high frequency board, and can receive and transmit the circularly polarized waves of different frequency bands through the slotpairs, so that the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a broadband planar antenna. Background technique [0002] With the continuous development of satellite navigation and measurement technology, satellite positioning systems have also been increasingly widely used, such as China's Beidou Navigation Satellite System (BDS), the United States' GPS (Global Positioning System, Global Positioning System) Wait. As these satellite systems continue to mature, and antennas are the key equipment for receiving satellite signals, antennas with high performance (such as broadband and high efficiency) have become the goals pursued by consumers. The microstrip antenna is a widely used antenna. However, the microstrip antenna usually needs to use a high-frequency board, and the cost is relatively high. Contents of the invention [0003] Based on this, it is necessary to provide a broadband planar antenna to solve the problem of high cost of th...
