In this paper, an endfire dual-polarized phased array is introduced for 5G mobile applications, which operates from 26 GHz to 30 with low profile of only 1.1 mm ( ${\bf 0.1\lambda _0}$ at GHz) and small clearance 3.5 mm. The consists in...

A node microstrip architecture is proposed for designing a compact Butler matrix (BM) that integrated with dual-polarized endfire antenna array. The can be used to form variety of 2 × port networks including, but not limited to, couplers and crossovers. By concatenating the together, BM any number ports formed. Using method, 4 operating in millimeter wave (mmWave) band designed size <inline-for...

A novel low-profile phased antenna with dual-port and its two types of 1-D linear array to 2-D space wide-angle beam scanning are proposed. The unit is composed fishbone structure rhombus parasitic patch, which folded into n-shaped low profile $0.08\lambda $ </te...

This article describes a dual-polarized endfire antenna array for millimeter-wave (mm-wave) frequencies. The consists of chain-slot-shaped pattern on mobile phone metal frame. is fed using transmission line, which would cause only negligible capacitive loading the sub-6 GHz realized same frame and, therefore, not significantly degrade its performance. makes colocating and mm-wave antennas in sa...

Abstract This paper investigates uni-/multi-cast and orbital angular momentum (OAM) mode data transmission in orthogonal directions by the utilization of a new circular antenna array, operating at 28 GHz. In horizontal plane proposed array operates as multimode transmitter (i.e., it provides broad-, uni- and/or multi-cast communication), while vertical direction OAM occurs is capable generating...

OBJECTIVE To evaluate the improvement in speech intelligibility in noise obtained with an assistive real-time fixed endfire array of bidirectional microphones in comparison with an omnidirectional hearing aid microphone in a realistic environment. DESIGN The microphone array was evaluated physically in anechoic and reverberant conditions. Perceptual tests of speech intelligibility in noise we...

AbstrAct: A scanning-beam antenna on metamaterial coplanar structures is presented. The proposed antenna is, in essence, a composite of Right/Left-Handed (CRLH) coplanar waveguide (CPW) structure incorporating distributed periodic structures with L-C high-pass filter topology which support left-handed (LH) waves. The negative refractive index (NRI) properties of these structures are shown theor...
