Printed Tem Horn Antenna Fed by Balanced Microstrip Line
Abstract—In this paper, a new kind of printed TEM horn antenna with high-gain fed by balanced microstrip line is proposed. The radiation part of the antenna (printed on the FR4 epoxy substrate) is composed of two symmetrical triangular metal foil branches fed by balanced microstrip line. The antenna has been simulated by CST MICROWAVE STUDIOr software and the simulated results show that the pro...
متن کاملTem Horn Antenna for Ultra-wide Band Microwave Breast Imaging
A novel TEM horn antenna placed in a solid dielectric medium is proposed for microwave imaging of the breast. The major design requirement is that the antenna couples the microwave energy into the tissue without being immersed itself in a coupling medium. The antenna achieves this requirement by: 1) directing all radiated power through its front aperture, and 2) blocking external electromagneti...
متن کاملCell Morphing: From Array Programs to Array-Free Horn Clauses
Automatically verifying safety properties of programs is hard. Many approaches exist for verifying programs operating on Boolean and integer values (e.g. abstract interpretation, counterexampleguided abstraction refinement using interpolants), but transposing them to array properties has been fraught with difficulties. Our work addresses that issue with a powerful and flexible abstraction that ...
متن کاملFocal-Plane Array Architectures: Horn Clusters vs. Phased-Array Techniques
The science goals of the SKA specify a field of view which is far greater than what current radio telescopes provide. Two possible feed architectures for reflector antennas are clusters of horns or phased-array feeds. This memo compares these two alternatives and finds that the beams produced by horn clusters fall short of fully sampling the sky and require interleaved pointings, whereas phased...
متن کاملInjection Molded Millimeter-Wave Horn Array Antenna
This paper shows injection molded millimeter-wave horn array antenna for the 1-dimensional APAA(Active Phase Array Antenna). The antenna is composed of horn antennas, grooved circular waveguide polarizers, E-plane T-junctions, and E-plane bends employing dielectric waveguides. This structure makes it possible to manufacture a feed circuit and radiating elements as an integrated unit by using in...
