Problems solved by technology

[0003] In the prior art, the slot of the slot antenna is usually linear. Due to the limitation of size, the linear slot is relatively short. When the current passes through the edge of the linear slot, the path it flows through is relatively short, resulting in low electromagnetic field strength around the slot. , especially low-frequency radiation efficiency is low, making the low-frequency bandwidth of the slot antenna narrow

Abstract

The invention discloses a microstrip slot antenna and signal transmission equipment, the microstrip slot antenna comprises a substrate, an antenna radiator is arranged on the front surface of the substrate, a reference ground plane is arranged on the back surface of the substrate, a bending slot is formed in the reference ground plane, and the bending slot is used for enhancing the radiation efficiency of the antenna radiator. Since the bending gap increases the current flowing path, the electromagnetic field intensity around the gap is increased, the area with high current density can be controlled in a specific area, the low-frequency radiation efficiency of the antenna is improved, and the low-frequency bandwidth of the antenna is increased. In addition, the signal transmission equipment disclosed by the invention comprises the slot antenna, and also has the above effects.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a microstrip slot antenna and signal transmission equipment. Background technique [0002] Antennas, especially slot antennas, are widely used in capsule endoscopes, implantable chips, miniature wearable devices, etc. The slot antenna has a coplanar structure, which is small in size and light in weight, and it is easy to implement a conformal design with the device. For implantable slot antennas, its characteristics may vary with different human bodies, and individual fat and height are also different, requiring the antenna to have ultra-broadband and multi-frequency performance, so that it can maintain signal transmission when used by different users stability. [0003] In the prior art, the slot of the slot antenna is usually linear. Due to the limitation of size, the linear slot is relatively short. When the current passes through the edge of the linear slot, the path it fl...
