A 60-GHz CMOS on-chip dipole antenna with efficiency-enhancement technique is presented. A helium-3 ion irradiation process is used to reduce the substrate losses of the on-chip antenna. The radiation efficiency of the antenna is doubled using the ion implantation technique. The antenna is fabricated in a 65-nm CMOS technology with a core area of 0.48 mm2. The on-chip antenna achieves a peak gain...
A novel polarization rotation surface based on artificial magnetic conductor structure (AMC) is proposed, which can reflect incident wave in orthogonal polarization state and simultaneously offer a 90° phase difference. The feature is theoretically analyzed and validated. By using the proposed polarization rotation AMC, right-handed circular polarization is achieved for a linearly polarized dipole...
A planar dipole antenna loaded with bandstop reflector is presented and investigated. The loading structure is composed of two symmetrically positioned twin lines. The loading structure acts as a bandstop filter in the corresponding frequency band, and meanwhile functions as a reflector in the operating frequency band, which is not a combination but an integration of reflector and bandstop filter...
In this paper design concepts for compact broadband printed V-Band 2×1 bowtie, 2×1 and 2×2 dipole array antennas, suitable for millimeter wave (mm-Wave) applications, are presented. The antennas are designed on a planar quartz glass substrate. The center frequencies of the array antennas are set to 60 GHz. Optimization techniques for improving antennas impedance matching and overall gain are also...
This paper presents an implementation study of a wireless communication network in Printed Circuit Board (PCB) context. First, we point out the needs and the constraints in term of communication for a Wireless Interconnect Network-on-Board (WiNoB). Then, we present the electrical characteristics of the chosen dipole and “Vivaldi” antennas for the achievement of a 10 GHz demonstrator. Finally, using...
