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°ϕ30°) and below -7 dB in the back lobe (90°ϕ270°).
