Novel Circularly Polarized Substrate Integrated Waveguide SLOT Antanna
Circularly-polarized antenna is built based on a new SIW (substrate integrated waveguide)structure which contains cavity-backed resonator and a conventional polarized ring with twosquare slits in inner and outer ring that differ 90° at position and is proposed for right-handedcircular polarization (RHCP) and fabricated in two separate layers. A broadband impedancebandwidth of 13.9% and a RHCP a...

متن کاملLTCC Partially-Filled Post-Wall Rectangular-Waveguide Slot Array Antenna in the Millimeter-Wave Band
In the millimeter-wave band, the series-fed array antenna is facing a problem of large transmission loss and narrow bandwidth by using a high-permittivity and large-loss-tangent material. In this paper, an air region is inserted in the half of the height in the LTCC waveguide of εr =6.6 and tanδ =0.013 to reduce the transmission loss. The reduction of the equivalent dielectric constant by the a...
متن کاملCircularly Polarized Circular Slot Antenna Array Using Sequentially Rotated Feed Network
This paper presents the design, simulation, and measurement of two low-cost broadband circularly polarized (CP) printed antennas: a single element and an array at C band. The proposed single element antenna is excited by an L-shaped strip with a tapered end, located along the circular-slot diagonal line in the back plane. From the array experimental results, the 3 dB axial ratio bandwidth can r...
متن کاملGHz AND 5 . 8 GHz COMPACT DUAL - BAND CIRCULARLY POLARIZED PATCH ANTENNA
A dual-band circularly polarized stacked microstrip antenna for ISM Bands (2.45GHz & 5.8GHz) applications is designed and implemented. By stacking two different corner-truncated square patches in a dielectric substrate layer, the microstrip antenna for dual-frequency circular polarization (CP) can be achieved with −11.5 dB and −12.8 dB measured return loss for 2.45GHz and 5.8GHz. Semicircular g...
