Algoritma genetik digunakan untuk mensintesis tatasusunan arka bulat berarah sebagai antena sektor. Kemudian, prestasi antena sektor ini dalam saluran gelombang milimeter wayarles dalaman disiasat. Berdasarkan corak yang dikehendaki dan topografi antena, masalah sintesis boleh dirumus semula menjadi masalah pengoptimuman dan diselesaikan oleh algoritma genetik. Algoritma genetik akan sentiasa menumpu kepada ekstrem global dan bukannya ekstrem tempatan dan mencapai penghampiran yang baik kepada corak yang dikehendaki. Seterusnya, tindak balas impuls saluran dalaman untuk mana-mana lokasi pemancar-penerima dikira dengan teknik tangkapan dan pantulan sinar/imej. Dengan menggunakan tindak balas impuls saluran berbilang laluan, prestasi antena sektor pada sistem BPSK (pengkunci anjakan fasa binari) dengan litar pemulihan fasa dan pemasaan dipersembahkan. Keputusan berangka menunjukkan bahawa antena sektor yang disintesis berkesan untuk memerangi pudar berbilang laluan dan boleh meningkatkan kadar penghantaran sistem gelombang milimeter dalaman.

Abstract: The genetic algorithm is used to synthesize the directional circular arc array as a sectored antenna. Then, the performance of this sectored antenna in indoor wireless millimeter wave channel is investigated. Based on the desired pattern and the topography of the antennas, the synthesis problem can be reformulated into an optimization problem and solved by the genetic algorithm. The genetic algorithm will always converge to global extreme instead of local extreme and achieves a good approximation to the desired pattern. Next, the impulse responses of the indoor channel for any transmitter-receiver location are computed by shooting and bouncing ray/image techniques. By using the impulse response of multipath channel, the performance of the sectored antenna on BPSK (binary phase shift keying) system with phase and timing recovery circuits is presented. Numerical results show that the synthesized sectored antenna is effective to combat the multipath fading and can increase the transmission rate of indoor millimeter wave system.
