Abstract

The invention discloses a broad band low profile conic sleeve monopole antenna which comprises a monopole (1), a conic top loading sleeve (2), a top loading disc (3), a floor (6), first short circuit probes (4), a second short circuit probe (5) and a radio frequency interface unit (8). The monopole (1) is placed perpendicularly to the floor (6). The top loading disc (3) is placed at the top of the monopole (1). The top loading disc (3) and the monopole (1) are connected through screws. The top loading disc (3) is used for top loading to the monopole (1). The top loading disc (3) and the floor (6) form a short circuit through four first short circuit probes (4). A conic sleeve is added to the monopole so that circular ring top loading is performed to the sleeve, and therefore impedance bandwidth of the antenna is broadened effectively and the dimension of the antenna is reduced.

Description

technical field [0001] The invention relates to a monopole antenna, in particular to a wide-band low-profile tapered sleeve monopole antenna. Background technique [0002] With the development of science and technology, the wireless communication industry has been greatly popularized, so people's requirements for the performance of antennas that are indispensable in wireless communication systems are also increasing, such as miniaturization, low profile, broadband and so on. As an omnidirectional antenna, the monopole antenna is widely used in practical applications due to its good reliability, high stability, simple structure, and low cost. [0003] In order to achieve the low profile of the monopole antenna, the usual method is to carry out top loading, but the top loading increases the lateral size of the antenna while reducing the height of the antenna; the thick dipole has a lower characteristic impedance and is asymmetric The structural form can play a role similar to...
