Fully Metallic One Dimensional Uniform Tapered-Pin Leaky-Wave Antenna at 30 GHz

Åkerberg, Henrik, Faghi, Puya January 2021 (has links)
This paper describes the design of a one dimensionalleaky-wave antenna, with an operating frequency at 30 GHz.The antenna consists a waveguide with one of the wallsreplaced by a semi-open row of pins, allowing power to leakout. The waveguide width and the height of the pins are taperedalong the waveguide length, in order to control the antenna’sradiation parameters.The antenna has been modeled and tested, using CST MicrowaveStudio and MathWorks Matlab. The final antenna designoperates at 30 GHz with an efficiency of 90%, side lobe levels of-26.3dB and a beamwidth 6.4°. For other frequencies in the Kaband the angle of maximum radiation varies, giving the antennascanning capabilities in one dimension. / Detta dokument beskriver utformningen aven endimensionell läckvågsantenn med en centerfrekvens på30 GHz.Antennen består av en vågledare där en av väggarna ersattsmed tappar som gör att effekt kan stråla ut. Vågledarens breddoch tapparnas höjd ändras längs vågledarens längd för attkontrollera antennens strålningsparametrar.Antennen har modellerats och testats med CST MicrowaveStudio och MathWorks Matlab. Den slutgiltiga antenndesignenfungerar vid 30 GHz med en effektivitet på 90%, sidlobsnivåerpå -26.3dB och en strålbredd på 6.4°. För andra frekvenser inomKa-bandet varierar vinkeln för maximal strålning, vilket tillåterantennen att scanna i en dimension. / Kandidatexjobb i elektroteknik 2021, KTH, Stockholm
