Design of a Pickett-Potter Horn to measure the CMB at 11 GHz

چکیده
In this Bachelor Thesis the design of a horn antenna to measure the Cosmic Microwave Background (CMB) at 11 GHz is discussed. The theory underlying the design and di↵erent horn antenna types are treated. From this the optimal horn design is chosen; the Pickett-Potter horn. Then the design is optimized with a bandwidth of 1 GHz using CST Microwave Studio. Having obtained the final design, the Pickett-Potter is constructed and tested for the beam pattern and the reflection of the probe. From this it can be seen that the measured beam pattern and probe reflection deviate from the simulations. This di↵erence is due to the propagation of a higher order mode. Despite this, the constructed Pickett-Potter horn was still suited for our observation, when rotated 90 .

Development of Low Profile Substrate Integrated Waveguide Horn Antenna with Improved Gain
In this paper a new low profile Substrate Integrated Waveguide (SIW) probe-fed H-plane horn antenna structure with improved gain is proposed. The proposed antenna consists of two waveguides including a rectangular and a taper one, in which both, first and third modes of the structure are simultaneously excited leading to a uniform field distribution along the radiating aperture of the antenna a...

This paper describes the design of an X-band balanced low noise amplifier (LNA) using an available HJFET device. The balanced LNA consists of a pair of electrically similar transistors whose input and output signals are divided or combined by 3 dB two-stage Wilkinson power dividers. The proposed balanced LNA is fabricated and measured. The measured results show that the noise figure is 1.30 dB ...
