Abstract

The invention discloses a balanced micro-strip line feeding printed V-shaped antenna with a loading metal disc, and relates to printed V-shaped antennas. The balanced micro-strip line feeding printed V-shaped antenna aims to solve problems that a traveling-wave working mode only can be implemented when a lossy terminal matched a load is added into the traditional traveling-wave antenna and a feeding structure is complicated. The balanced micro-strip line feeding printed V-shaped antenna is characterized in that a first feeding structure is printed in the middle of the upper end of the front surface of a dielectric slab linearly from top to bottom, a second feeding structure is printed in the middle of the upper end of the back surface of the dielectric slab linearly from top to bottom, a first radiation unit and a second radiation unit are arranged in the middle of the front surface of the dielectric slab and form a herringbone, the upper end of the first radiation unit is connected with the lower end of the first feeding structure, the loading metal disc is arranged between the lower end of the first radiation unit and the lower end of the second radiation unit, and a plated-through via hole is arranged at the upper end of the second radiation unit and sequentially runs through the second radiation unit, the dielectric slab and the second feeding structure. The balanced micro-strip line feeding printed V-shaped antenna is used in the radio field.

Description

technical field [0001] The invention relates to a printed V-shaped antenna, in particular to a printed V-shaped antenna fed by a balanced microstrip line and loaded with a metal disc. Background technique [0002] UWB directional antenna has a wide frequency band and good directivity, and can transmit data at high speed in wireless communication, so it has been widely used. The UWB directional printed antennas currently proposed mainly include log-periodic antennas, Archimedes spiral antennas, equiangular spiral antennas, butterfly antennas, tapered slot antennas, and TEM horn antennas. In order to achieve the directivity of the antenna, the antenna designer generally adopts the following methods: 1. For the omnidirectional antenna, the directional radiation is realized by forming an array or adding a metal reflective surface, typically a butterfly antenna, but this will introduce complex feeding Network; 2. The logarithmic periodic antenna is fed from one end of the short ...
