🔍 Analyzing the Operating Mode of Spiral Antennas 📡 Many antennas deployed in basic communication systems are linearly polarized, which means that polarization is limited to a single plane in terms of electric field direction. The antenna that can generate circularly polarized electromagnetic waves can give us more choices, because the polarization of the wave will change in the process of propagation, for example, the spiral antenna can generate circularly polarized waves in the axial operating mode. RF simulation can be used to optimize spiral antenna design. 👉 https://buff.ly/3Sqpk3e #GNSSAntenna #SpiralAntenna #CircularPolarization #RFSimulation #TechInnovation #WirelessCommunication #AntennaDesign #EngineeringInsights

Hi All, Some of you may know about the TearDown on StarLink Dish Phased Array (User Terminal) posted on: https://lnkd.in/dPMnmK3f Did you know about the use of Cross-Shaped Parasitic Elements shown in the image below? What is this for? 1) Improving Bandwidth: Broadband Characteristics: Cross-shaped parasitic elements help in achieving broader bandwidths. The multiple arms of the cross provide multiple resonant paths, which can be designed to cover a wider frequency range. This is particularly beneficial in Ku-band applications where the antenna needs to operate efficiently across 10.7-12.7 GHz and 14.0-14.5 GHz. 2) Enhancing Polarization: Dual Polarization: Cross-shaped elements can support dual polarization (both horizontal and vertical), which is crucial for satellite communications to reduce signal degradation and improve overall link reliability. This allows the antenna to handle multiple polarizations simultaneously, thereby improving signal quality and data throughput. 3) Improving Radiation Pattern: Sidelobe Reduction: The cross-shaped parasitic elements help in shaping the radiation pattern of the antenna, particularly in reducing sidelobes. Sidelobes can lead to interference and reduced efficiency, so controlling them is critical for optimal antenna performance. 4) Beam Shaping: These elements can aid in controlling the main lobe of the radiation pattern, allowing for more precise beam steering and better alignment with the moving satellites. 5) Technical Mechanisms: Resonant Paths: The cross shape introduces multiple resonant paths, which help in broadening the operational bandwidth and supporting multiple frequencies. Inductive and Capacitive Effects: The arms of the cross can introduce inductive and capacitive effects, which can be finely tuned to achieve the desired impedance matching and bandwidth characteristics. 6) Compact and Efficient Design: Cross-shaped elements contribute to a more compact antenna design by integrating multiple functionalities (like dual polarization and multiband support) into a single element. This helps in keeping the antenna size manageable while enhancing its performance. Please add comments if I miss something. Have a wonderful weekend!

My first step in 10 GHz band ! 🛰 Today, communication is increasingly happening via satellites. Using and navigating this technological advancement is of utmost importance for us. Therefore, I'm delighted to announce the addition of a 10GHz (3cm) X-band receiver to my amateur radio station. This receiver is designed to receive signals from satellites or ground stations transmitting in the #Xband. Allow me to provide you with more details about this station. As you might be aware, the setup includes an #LNB (low-noise block downconverter), a parabolic reflector #antenna with an approximate gain of 35 dB, and an SDR(Software Defined Radio) receiver. The primary goal is to listen to the amateur radio #transponder on the Es'hail 2 (QO-100) #satellite, which broadcasts at 10GHz. The distance of the Es'hail 2 satellite from Earth is 35,786km. The LNB is powered through a bias tee circuit, which I have designed using the #EasyEDA program. This circuit's purpose is to allow the DC current to pass through a coil, transmitting it to the LNB via the coaxial cable. On the receiver end, a coupling capacitor is utilized to block the DC current. The S²¹-Insertion loss of the bias tee circuit at 1GHz was measured as 0.25 db by #VNA. I used lnb with #pll oscillator instead of dro to ensure frequency #stability and less frequency drift due to temperature change. In addition, np0 type ceramic capacitor is used in the bias circuit to prevent the circuit from being affected by heat. Utilizing the LNB, the 10.489GHz satellite #broadcast frequency is reduced by 9.75GHz and then passed through a 20 dB attenuator that I produced in my laboratory. This allows the signal to be received at around 739 MHz by the #SDR receiver. A phone app was used to detect the azimuth angle of the satellite and a garmin #GPS device with a built-in compass sensor (don't forget to enter the magnetic declination angle of your location on the device, about 4° east for me) was used to rotate the antenna to the detected position. Thank you to TA2NC, who produced and operated the first 10GHz ground #beacon of Turkey, for allowing me to calculate the lnb and SDR frequency shift and adjust my various settings to a reference signal source. With this project my station became one of the few amateur radio stations that can work with 10GHz in Turkey. It was a very useful work to provide my amateur radio station with satellite communication capability, which is very important for #emergency and disaster #communication. This project covers various topics, including SDR technology, attenuators, high-gain parabolic reflector antennas, bias tee supply circuits, amateur satellite communication, and the X-band 10GHz (3 cm) frequency range. My next target is making a transmitter working at 10GHz. TA2SEB 73 #amateurradio #pcb

The progress in the Si-Ge BiCMOS technology allows the integration of complete radar transceivers at frequencies around 300 GHz on one MMIC. The wide absolute bandwidth achievable in this frequency range has the potential to address the demand for high resolution imaging radar. In his new journal article, Adolfo Di Serio presents a solution to realize a MIMO radar at 300 GHz, overcoming the challenges related to the antenna deployment. The proposed system is characterized by a low-cost antenna front-end, which is connected to the MMIC-integrated radar transceivers using dielectric waveguides (DWG). The mechanical flexibility of the DWGs together with an easy interconnection structure enable the possibility of using the designed platform as a testbed for 1-D and 2-D MIMO arrays. Such a system represents a breakthrough for the validation of MIMO arrays in the sub-millimeter wave frequency range.
