Abstract

The invention discloses a frequency and polarization programmable patch antenna. The frequency and polarization programmable patch antenna comprises a first metal covering layer, a medium layer, a second metal covering layer and four metalized through holes, which are arranged sequentially from top to bottom, wherein the first metal covering layer comprises a feeder line and a radiation patch; the feeder line comprises a microstrip line which is connected with an external feed port; the microstrip line is connected with one side of the radiation patch through a high-resistance line; the radiation patch is a square metal patch; a gap is etched on the other side, close to the radiation patch, of the radiation patch, namely the position of a radiation side; the gap is parallel to the radiation side; the metalized through holes are formed in the two sides of a gap bent part and the two ends of the metalized through holes are connected with the first metal covering layer and the second metal covering layer respectively; the metalized through holes are provided with switches respectively; when a certain switch is conducted, the first metal covering layer is connected with the metalized through hole controlled by the switch and the second metal covering layer. The frequency and polarization programmable patch antenna has the beneficial effects that the programmable antenna has a simple structure of a feed network, a small volume and more working patterns.

Description

technical field [0001] The invention belongs to the technical field of antennas and relates to a patch antenna with programmable frequency and polarization. Background technique [0002] With the rapid development of wireless communication systems, antennas, as a key component, need to be able to adapt to changing environments and have a smaller design space. In order to improve the information capacity and the adaptability of the antenna to the environment, a reconfigurable design is required. Programmable antenna is a realization method of reconfigurable antenna. Firstly, as many working modes as possible should be constructed on a single antenna. Secondly, each working mode can be selected through one or more switches. By programming the switch state The control can realize the flexible switching between various working modes. Compared with ordinary reconfigurable antennas, the advantages of programmable antennas are that there are many possible working modes and they c...
