The invention relates to a multiband dish antenna based on a novel combined loading method. The multiband dish antenna is composed of a microstrip-to-balance two-wire feeder line, triangular radiation arms and a dielectric substrate. An upper transmission line is located on the upper surface of the dielectric substrate and is connected to an upper triangular radiation arm. A lower transmission line is located on the lower surface of the dielectric substrate and is connected to a lower triangular radiation arm. An upper open annular slot is loaded on the upper triangular radiation arm. A lower open annular slot is loaded on the lower triangular radiation arm. The upper triangular radiation arm and the lower triangular radiation arm intersect to form an angular apex. A parasitic fractal multi-triangle is loaded in the front-end area of the angular apex. The multiband dish antenna effectively reduces the mutual influence between various frequency bands, ensures the performance indexes of the respective frequency bands, and solves the narrow bandwidth of the pure slot loading.
Description
technical field [0001] The invention relates to a multi-band dish antenna based on a new combined loading method. Background technique [0002] Multi-frequency antennas are one of the research hotspots in the field of antennas in recent years. The use of multi-frequency antennas can effectively reduce the number of antennas and reduce the interference between antenna systems in different frequency bands, so as to improve performance, save space and cost. With the development of various multi-frequency antenna theories and technologies, a series of multi-frequency antenna implementation methods and measures have been developed, such as resonance stub loading technology, slot loading technology and fractal technology. [0003] Common multi-frequency antennas include vibrators, patches, and butterfly antennas. Among them, the butterfly antenna is widely used in engineering. By loading one or more rectangular or circular slots on the radiation arm of the butterfly antenna, a new...
