چکیده
In this article, a 5G compact millimeter-wave dipole antenna with high gain and its array filter-antenna is proposed, following theoretical discussion proposed. To increase the focused mainbeam, double inserted at ground plane. The results show that proposed has an impedance band-width (IBW) of around 7.14% 6.7 dBi 28 GHz. Next, filter 4% IBW lower than 0.6 dB insertion loss. A simple phase-shifter 2-bit structure designed in 8-elemens $0.35\lambda $ spacing between two elements which uses meander-line to reduce mutual-coupling. First, phased-array filtenna (filter-antenna) fabricated meet analog beamforming challenge. IBWs are approximately 3.5% 15 dBi. Second, novel machine learning method as alternating direction multipliers Bayesian Optimization (ADMM-BO) used hybrid for such partially-connected structures. Simulation measurement have acceptable data rates. data-rates reach 100 Mb/s SNRs higher 10 dB. amount 0 SNR 75 Mb/s. These also indicate mainbeam shift range [−50°, 50°] variations 1.5 side lobe level (SLL) about −10 50°.

This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...
متن کاملFast Beamforming of Compact Array Antenna
In this chapter, we describe a compact array antenna. Beamforming is achieved by tuning the load reactances at parasitic elements surrounding the active central element. The existing beam forming algorithms for this reactively controlled parasitic array antennas require long training time. In comparison with these algorithms, a faster beamforming algorithm, based on simultaneous perturbation st...
