چکیده
A wideband vertically-polarized end-fire magneto-electric (ME) dipole antenna fed by an asymmetrical substrate integrated coaxial line (ASICL) is proposed for millimeter-wave (mm-wave) applications. The ME has impedance bandwidth of 60% and produces radiation with a stable gain between 5.8 6.9 dBi in simulation. To verify the design concept its application arrays, 1 × 8 linear array fixed beam 4 multiple beams are designed, fabricated measured. fixed-beam prototype exhibits 62%, peak 15.9 efficiency 79%. multi-beam ASICL Butler matrix. Experimentally, excellent scanning patterns reasonably low side lobes cross polarizations demonstrated at 24, 30 36 GHz. And overlapped operating 28.6% achieved prototype.

Miniature 250 to 700-μm tall copper air-filled rectangular coaxial line with inner conductor supported by periodic dielectric straps is demonstrated. The measured loss is as low as 0.08dB/cm at 37GHz, while the isolation between two parallel lines with center-to-center separation of 350μm is better than 60dB. A number of quasi-planar components are designed to be fabricated on the same 6inch wa...
متن کاملFundamental characteristics of a planar folded dipole antenna with a feed line on the dielectric substrate
Recently, the many services for the cellular phone are spread. Therefore, the broadband antenna for handsets is required. In our previous paper [1], the planar folded dipole antenna (PFDA) with a feed line, which consists of two parallel lines has been introduced and its characteristics have been analyzed. As a result, it was found that PFDA with a feed line had a broadband characteristic and t...
متن کاملMillimeter-Wave Device-to-Device Networks with Heterogeneous Antenna Arrays
Millimeter-wave (mm-wave) device-to-device (D2D) communication is considered one of the most promising enabling technologies to meet the demanding requirements of future networks. Previous works on mm-wave D2D network analysis mostly considered the case that all devices were equipped with exactly the same number of antennas, whereas real networks are more complicated due to the coexistence of d...
