Abstract A beamwidth (BW) and beam direction (BD) reconfigurable antenna based on multi‐mode parasitic coupling is proposed. Two pairs of metal strips connected by only two positive‐intrinsic‐negative diodes are added as parasitic structures ov

This paper presents an antenna that utilizes two beam steering techniques in concert in order to improve the antenna gain and steering resolution. Phased array steering is employed to achieve coarse resolution beam steering while parasitic steering i

An antipodal Vivaldi antenna with a compact parasitic patch to overcome radiation performance degradations in the high-frequency band is proposed. For this purpose, a double asymmetric trapezoidal parasitic patch is designed and added to the aperture

Antenna arrays are commonly used to achieve high gains and beam steering, but they require complex feeding networks. For applications demanding moderate antenna gains (≃6 dB) and planar radiating structures, printed Yagi-Uda antennas can offer many

In this paper, a super directive four-element compact parasitic antenna array has been designed and optimized using an ad hoc procedure based on the Harrington maximum directivity definition and spherical wave expansion. The complete design procedure
