Pattern Optimisation of a Yagi-Uda Antenna
Optimise a Yagi-Uda antenna design to achieve a specific radiation pattern and gain at 1 GHz. The Yagi-Uda antenna consists of a dipole, reflector and two directors.
The initial antenna design is created from basic formulae.
The antenna design is then optimised to obtain a gain above 8 dB in the main lobe
(-30°≤ϕ≤30°)
and below -7 dB in the back lobe (90°≤ϕ≤270°).
