Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to a universal rod antenna. Background Technology

[0002] Antenna equipment is widely used in fields such as communications, radar, and electronic warfare. Any device that uses electromagnetic waves to transmit information and energy relies on antenna devices. Antennas come in many forms and types, with common types including various rod antennas, planar antennas, horn antennas, and combinations and arrays of them. For rod antennas, in addition to meeting electrical performance requirements, they must also meet the additional requirements of ease of installation, neat appearance, and small size.

[0003] Currently, most omnidirectional radiating rod antennas are designed with fixed structures and mostly use monopole or dipole antenna designs. However, since the gain of a single monopole or dipole antenna is low, technicians usually add external gain circuits to compensate for the lack of gain. However, adding external gain circuits increases the manufacturing cost of the antenna in the research and development, design, and subsequent processing. Therefore, it is necessary to propose improvements to the current traditional rod antennas to solve their problems. Utility Model Content
