Series-Fed Millimeter-Wave Antenna Array Based on Microstrip Line Structure

open access: yesIEEE Open Journal of Antennas and Propagation, 2023
This paper presents a millimeter wave series-fed microstrip line antenna array with low side lobes. For millimeter-wave beam forming applications, compact series fed arrays with very small horizontal width and low side lobes are very much required.

Beamforming Network Design Utilizing Node Microstrip Architectures for Dual-Polarized Endfire Millimeter-Wave Antenna Arrays

open access: yesIEEE Transactions on Antennas and Propagation, 2023
A node microstrip architecture is proposed for designing a compact Butler matrix (BM) that is integrated with a dual-polarized endfire antenna array. The node microstrip architecture can be used to form a variety of compact 2 × 2 port networks including,

5G mmWave patch antenna array with proximity sensing function for detecting user's hand grip on mobile terminals

open access: yesElectronics Letters, 2023
We propose a new concept millimetre‐wave patch antenna that integrates the functions of an antenna and a capacitive proximity sensor to detect the hand grip state for 5G mobile terminals and compensate for the hand effect.

Microstrip adaptive array antenna

open access: yesElectronics Letters, 1996
A planar adaptive array of three microstrip patch antennas consisting of a central active microstrip antenna and two symmetrical lateral passive antennas is used to steer the beam. An electronic beam scanning of /spl plusmn/20/spl deg/ can be achieved with the control of reactive loads located into the lateral patches.
