Novel multiband high-gain hexagonal slotted microstrip patch antenna

Abstract

The invention relates to the field of multi-band and high-gain antennas. A novel multiband high-gain hexagonal slotted microstrip patch antenna comprises a prepared tabulate dielectric substrate 1 with a dielectric constant of 2.2, a regular hexagonal metal plate radiation unit 2 located on the upper surface of the dielectric substrate 1, a metal connecting bottom plate 3 located on the lower surface of the dielectric substrate 1, and a coaxial feed probe 4, wherein six hollowed-out slots with 120-degree angles are formed in the edges of the radiation unit 2, the 120-degree angle of each slot corresponds to an inner angle of the radiation unit 2, two sides of each 120-degree angle are respectively parallel to two sides of the corresponding inner angle of the radiation unit 2, the two adjacent slots are not contacted, an outer core of the coaxial feed probe 4 is connected with the dielectric substrate 1 and the metal connecting bottom plate 3, and an inner core of the coaxial feed probe 4 is connected with the radiation unit 2.

Description

technical field [0001] The present invention relates to the field of multi-band high-gain antennas. Background technique [0002] With the rapid development of contemporary wireless communication systems, especially the substantial increase in communication rates, the requirements for antenna performance are getting higher and higher. Microstrip antenna is widely used in various occasions of modern communication due to its advantages of low profile, low cost, easy conformation with the carrier, and convenient integration. Due to the low gain and single frequency band of traditional microstrip patch antennas, their widespread use is limited. Therefore, improving the gain of the antenna and expanding the number of frequency points has become a research hotspot. The research on microstrip patch antennas is also constantly innovating and developing. Several techniques have been proposed to increase the gain and expand the number of frequency points, thereby Improve antenna per...
