Embodiment Construction

[0016] The design will be further described below in conjunction with the accompanying drawings of the description.

[0017] Such as figure 1 As shown, a dual-frequency reconfigurable microstrip slot antenna is characterized in that: it includes a dielectric substrate 3, a slot 1 with a length greater than its width is arranged on the dielectric substrate 3, and at a certain distance from the left end of the slot 1 A metal strip 2 is provided, one end of the metal strip 2 is connected to the floor, one end is connected to the RF-MEMS switch, and the other end of the RF-MEMS switch is connected to the floor, at a certain distance from the right end of the gap 1 A microstrip line 4 is provided.

[0018] The resonant frequency of the microstrip slot antenna mainly depends on the length of the slot, and different operating frequencies can be obtained by changing the length of the slot.

[0019] A thin metal strip, one end of which is connected to the floor, and the other end is ...

Abstract

A dual-frequency reconfigurable micro-strip slot antenna is characterized by comprising a medium substrate, a gap with the length larger than the width is arranged on the medium substrate, the position which is a certain distance away from the left end of the gap is provided with a metal ribbon, one end of the metal ribbon is connected with a floor, the other end of the metal ribbon is connected with an RF-MEMS switch, the other end of the RF-MEMS switch is connected with the floor, and the position which is a certain distance away from the right end of the gap is provided with a micro-strip line. The resonant frequency of the micro-strip slot antenna mainly depends on the length of the gap, the principle that different working frequencies can be obtained by changing the length of the gap is utilized, and therefore the working frequency, the polarization direction and the radiation direction of the antenna are changed in real time by changing the structure and the position of an antenna radiation unit under the condition that the size of the whole antenna is not changed, the integration of the system antenna is achieved, and the size of the system is reduced.

Description

technical field [0001] This design involves a dual-frequency reconfigurable microstrip slot antenna, which belongs to the field of radio frequency electronic technology. Background technique [0002] With the development of wireless communication technology, many application systems (such as cellular phone, satellite communication and wireless local area network, etc.) can be integrated into one application platform. Most of these systems work in different frequency bands, and the antennas they use are also different in size and structure. If the discrete antenna is still used after the application system is integrated, the volume of the whole system has not been greatly improved. Therefore, multifunctional antenna design becomes an important research field. A reconfigurable antenna is a kind of multifunctional antenna. It can change the antenna's working frequency, polarization direction and radiation direction in real time by changing the structure and position of th...
