Study of dual-band horn antenna for parabolic reflector in 12- and 21-GHz-band satellite broadcasting reception

نویسندگان

چکیده

Satellite broadcasting of UHDTV in Japan has used the 12-GHz band (11.7 to 12.75GHz) since 2018. The 21-GHz (21.4 22.0GHz) also been allocated satellite Europe, Africa, and Asia Pacific. BSAT-4a not only 12-GHz-band transponders for services, but 21-GHz-band experimental future services. To receive services using these two frequency bands with a single antenna, we designed 12- dual-band horn antenna choke as feed parabolic reflector antenna. Simulation results showed that an aperture efficiency more than 70% was obtained both bands.

Substrate Integrated Waveguide Horn Antenna for 60 Ghz Band

The paper presents the design and fabrication of a H-plane substrate integrated waveguide (SIW) horn antenna. The antenna operates at 60 GHz band and is equipped with a SIW-to-WR15 transition. Experimental results prove that the antenna achieves the gain of 11.5 dBi and the impedance bandwidth of 14 % for the reflection coefficient less than -10 dB. The antenna was designed with the help of CST...

Dual Band Slotted Patch Antenna for On/Off-body Communication

Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...

Dual-Band Annular-Ring Microstrip Patch Antenna for Satellite Applications

A dual-band circularly polarized antenna fed by four apertures that covers the bands of GPS, Galileo, is introduced. The ARSAs designed using FR4 substrates in the L and S bands have 3-dB axial-ratio bandwidths (ARBWs) of as large as 37% and 52%, respectively, whereas the one using an RT5880 substrate in the L band, 61%. In these 3-dB axial-ratio bands, impedance matching with VSWR<=1.8 is also...

Modified U-Slot Stacked Micro-Strip Patch Antenna for Ultra-Wideband Applications in S Band, C Band and X Band

The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...
