Abstract

The invention discloses a double-band coplanar common-caliber base station antenna. The double-band coplanar common-caliber base station antenna comprises a feed circuit board (2), a reflection floor(3), a dipole antenna (5) printed on a first medium substrate (4) and a suspended patch antenna (6). Antennas can be applied to microwave millimeter wave communication systems, especially the double-band coplanar commoncaliber base station antenna. The double-band coplanar commoncaliber base station antenna has advantages of low profile height, planarization, light weight, low cost and short processing period.

Description

technical field [0001] The invention belongs to the technical field of microwave antennas, in particular to a dual-band co-planar co-aperture base station antenna in microwave antennas. Background technique [0002] With the rapid development of modern communication systems, mobile base stations are also developing in the direction of low profile, miniaturization, light weight, and low cost. The dual-band or even multi-band coplanar antenna is a low-profile, multi-frequency, multi-mode, low-cost integrated antenna suitable for mobile base stations produced under this situation. The dual-band coplanar base station antenna meets the needs of mobile While meeting the multi-frequency and multi-mode requirements of the base station, it greatly improves the cost and space waste caused by the non-coplanar design of the high and low frequency band antennas in the traditional base station. [0003] In the traditional base station antenna design, the high frequency band and low frequ...
