Abstract

The invention belongs to the communication field, and specifically relates to a compact multiband antenna comprising a medium substrate 105, a T-type microstrip transmission line arranged on the medium substrate, a first rectangular radiation unit 102, a second S-type radiation unit 103, a third S-type radiation unit 104, and a ground surface 106 arranged below the medium substrate; the first rectangular radiation unit 102 is etched with an E-shaped groove, and connected with the third S-type radiation unit 104 via the T-type transmission line; the bottom of the T-type transmission line is connected with an inner conductor of a connector; an outer conductor of the connector is connected with the ground surface 106. The compact multiband antenna employs the T-type microstrip transmission line to feed, radiation units are directly and indirectly combined to feed, and the multi radiation units are fused to realize the antenna multiband design, thus obtaining low profile and miniaturization design effects.

Description

Technical field [0001] The invention belongs to the field of information and communication, and specifically relates to a compact multi-band antenna. Background technique [0002] Since the beginning of the 20th century, with the rapid development of information technology, electronic communication, and multimedia technology, people have increasingly demanded high-speed, large-capacity, and high-performance mobile communication systems. The communication transmission rate of mobile terminal equipment is gradually increasing, and communication protocol standards are increasing. Therefore, the antenna in the terminal equipment is required to cover different working protocol standards and working frequency bands. However, due to the relatively small volume of mobile terminal equipment, the design of multiple transceiver antennas is obviously restricted by space and is prone to coupling effects, which seriously affects the communication quality. On the other hand, the rapid developm...
