Noise figure is noise factor expressed in decibels (dB). The noise factor equation shows that stage 1 has the most influence in the overal noise factor/figure of a system. As a result, to reduce the total noise figure the first stage device should have low-noise and relatively high gain. Calculate the antenna impedance over the range of 2.5 GHz to 11 GHz. For the purpose of executing this example, the impedance analysis has been precomputed and save in a MAT-file. ...

The antenna was fabricated on an Arlon Di 880 substrate, 0.254 mm thick, with \( \varepsilon_{r} = 2.2 \). The antenna generated a fan beam and the measured 3 dB beamwidths were 8.6° and 68° for the E- and H-planes, respectively. E-plane sidelobe levels peaked at −20 dB and the measured cross polarization was at most −28 dB.
Length: Microstrip Patch Antennas (or simply patch antenna) are increasingly useful because the antenna is printed directly onto a circuit board. Additional benefits of patch antennas is that they are easily fabricated making them cost effective. Their low profile design, often square or rectangular, allows them to be mounted to flat surfaces.
A short dipole is a dipole formed by two conductors with a total length that is significantly shorter than a half wavelength. For applications where a full half-wave dipole would be too large, short dipoles are more suitable. In a short dipole antenna, the feed impedance increases and its response is less dependent upon the frequency changes.
