     FDTD geometry mesh showing bowtie antenna with slots and loading resistors.
 
-The bowtie design features 3 slots in each arm of the bowtie where 3 different values of loading resistors are placed. In each slot there are 4 resistors of the same value, and each resistor is modelled as two parallel edges of a cell. The bowtie is placed on a lossless substrate that has a perimittivity of 4.8. The antenna is modelled in free space, and an output point (the electric field value) is specified at a distance of 60 mm from the feed of the bowtie (red coloured cell).
