| Summary: | A hybrid antenna is used to design a mixer in the
heterodyne receiver for THz range application to increase the
system efficiency. Design of a high precision THz range antenna
for a constant far-field beam pattern is always a challenging task
to the design engineers. A design procedure of THz band antenna
by using CST Microwave Studio has been presented. The
antenna has been designed and optimized to achieve constant far
field beam as well as fixed polarization. Beam patterns,
maximum directivity, on band directivity flatness, polarization,
Φ = 0
0
and Φ = 90
0
beam symmetries have been studied for 5mm
hemispherical lenses over WR-1.5 band (500GHz to 750GHz).
Experimental results show a better matching accuracy within the
design considerations. |
