An Overlapped Switched-Beam Antenna Array With Omnidirectional Coverage for 2.4/5.8 GHz Three-Channel MIMO WLAN Applications
Bibliographic record
Abstract
In the design of smart antenna, switched-beam technology is widely used to increase the communication capacity and to reduce electromagnetic interference. This letter presents a switched-beam antenna array for the three-channel multiple-input-multiple-output (MIMO) wireless local area network operating in 2.4/5.8 GHz. In the proposed array, there are 12 directional beams, and every four partially overlapped beams form a channel. Thus, the proposed array provides three channels. For each channel, the four antenna elements used to radiate directional beams are rotationally symmetrical. Therefore, for all channels, good omnidirectional coverage is obtained by dynamically switching directional beams. To demonstrate the effectiveness and advantages of the proposed array, a prototype is fabricated and measured. In it, the peak gain of directional radiation reaches 9.5 dB, and the values of the horizontal plane fluctuation for three channels are smaller than 5 dB.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
