Embodiment 1

[0026] refer to Figure 1-4 , a miniaturized dual-frequency microstrip array antenna, comprising: a mobile base 101, a support column 102, a support chassis 103 and a pressure-bearing chassis 104; The inner bottom side of the support column 102 is in contact with the inner upper surface of the expansion limiting mechanism, and the upper end of the support column 102 is fixedly connected with the inner shaft center of the support chassis 103. The support chassis 103 is ring-mounted and fixedly installed with 8 sets of embedded installation blocks 106, The embedded installation block 106 is provided with an embedded groove 108 that matches the snap-in rod 107, and the inner side of the snap-in rod 107 is movably socketed inside the embedded groove 108, and two groups of snap-in rods 107 are fixedly installed on the outer side The torsion spring 109, the other end of the torsion spring 109 is fixedly connected to the left and right sides of the upper end of the rotating protectiv...

Embodiment 2

[0030] Embodiment 2: Based on Embodiment 1, but different again is;

[0031] The upper and lower sides of the inside of the embedded groove 108 are located at the left and right sides of the middle part to be provided with limiting grooves 201, and the upper and lower sides of the inside of the clamping rod 106 are arranged with fixed grooves 202 at the left and right sides of the middle part. The upper end of 203 is fixedly connected with the inner end of the clamping block 204 , the clamping block 204 is movably socketed inside the fixing groove 202 , and the clamping block 204 matches with the limiting groove 201 .

[0032]During use, an embedded installation block 106 is also provided on the support chassis 103. By using modular installation, when a certain dual-frequency microstrip array antenna module 111 is damaged, it can be replaced by modular installation. Pull out the snap-in rod 107 externally to separate the snap-in rod 107 from the insertion groove 108, and then ...

Embodiment 3

[0033] Embodiment 3: based on Embodiment 1 and 2, but different again is;

[0034] The deployment buffer mechanism includes: a rotating rod 301, a linkage rod 302, and a fixed base 303. The rear middle part of the dual-frequency microstrip array antenna module 111 is movably connected to the outer end of the rotating rod 301 through a rotating shaft, and the inner end of the rotating rod 301 is connected to the linkage rod. The outer end of 302 is movably connected through the rotating shaft, and the inner end of the linkage rod 302 is movably connected with the outer side of the fixed base 303 through the rotating shaft, and the fixed base 303 is fixedly sleeved on the support column 102 .

[0035] The expansion limiting mechanism includes: a rotating plate 401, a limit spring 402 and an anti-collision plate 403. The lower end of the pressure bearing rod 105 is movably connected with the upper surface on the inner side of the rotating plate 401. The rotating plate 401 is provi...

Abstract

The invention discloses a miniaturized double-frequency microstrip array antenna, and belongs to the field of double-frequency microstrip array antennae. The miniaturized double-frequency microstrip array antenna is used in three forms, the miniaturized double-frequency microstrip array antenna is placed at a use position when the miniaturized double-frequency microstrip array antenna is just used, and when signal transmission needs to be enhanced, the miniaturized double-frequency microstrip array antenna can be used by taking down a movable base; at the moment, a rotary protective sleeve can be unfolded through a torsion spring arranged on the rotary protective sleeve, the dual-frequency microstrip array antenna module can be driven to be unfolded after the rotary protective sleeve is unfolded, and the dual-frequency microstrip array antenna module is completely unfolded in a second state used by the device, so that the signal transmission function is enhanced; and when the terrain is low and influences signal transmission, the movable base can be reversed and is in butt joint with a threaded groove formed in the bottom of the pressure-bearing chassis, at the moment, the movable base is in a third state, the height of the device can be increased, signal transmission can be enhanced, the three states can be adjusted according to the use requirements of the device, and the use requirements of the device are met.

Description

technical field [0001] The invention relates to the field of dual-frequency microstrip array antennas, in particular to a miniaturized dual-frequency microstrip array antenna. Background technique [0002] With the advancement of technology, wireless local area network (WLAN) has been widely used and developed rapidly due to its flexibility and convenience. In terms of frequency allocation, in the original 802.11b (2.4-2.483GHz) protocol, the limited bandwidth and transmission rate can no longer meet today's data communication needs, so the 802.11a (5.15-5.85GHz) protocol with a relatively abundant frequency band must be used . In order to meet the compatibility, the wireless local area network needs to adopt the dual-band transceiver system. [0003] The antenna is an important radio equipment in the communication system, and its performance will directly affect the performance of the radio equipment. Microstrip antenna has many advantages, such as small size, light weig...
