  • Using metasurfaces to improve gain and isolation of wideband PCB antennas for 5G sub-6 GHz communications systems

    Using metasurfaces to improve gain and isolation of wideband PCB antennas for 5G sub-6 GHz communications systems

    This work proposes a compact integrated multi-input multiple-output (MIMO) metasurface (MS) wideband antenna for sub-6 GHz fifth generation (5G) wireless communication systems. The obvious novelty of the proposed MIMO system is its wide operating bandwidth, high gain, small intercomponent cleara...

  • Why are there different frequency combinations for combined antennas?

    Why are there different frequency combinations for combined antennas?

    Ten years ago, smartphones typically supported only a few standards operating in the four GSM frequency bands, and perhaps a few WCDMA or CDMA2000 standards. With so few frequency bands to choose from, a certain degree of global uniformity has been achieved with “quad-band” GSM phone...

  • What is the 5G NR Wave signal chain?

    What is the 5G NR Wave signal chain?

    Millimeter wave signals provide wider bandwidth and higher data rates than low frequency signals. Take a look at the overall signal chain between the antenna and the digital baseband. New 5G radio (5G NR) adds millimeter wave frequencies to cellular devices and networks. Along with this comes an...

  • 5G Technology Competition, Millimeter Wave and Sub-6

    5G Technology Competition, Millimeter Wave and Sub-6

    The battle for 5G technology routes is essentially a battle for frequency bands. At present, the world uses two different frequency bands to deploy 5G networks, the frequency band between 30-300GHz is called millimeter wave; the other is called Sub-6, which is concentrated in the 3GHz-4GHz frequ...

  • What factors affect the performance of GPS antennas?

    What factors affect the performance of GPS antennas?

    The quality of the ceramic powder and the sintering process directly affect the performance of the gps antenna. The ceramic patch currently used in the market are mainly 25×25, 18×18, 15×15, and 12×12. The larger the area of the ceramic patch, the greater the dielectric constant, the higher the ...
