1, volume model of STLP antenna shows more satisfactory results, reaching GDM value of 0.144 for antenna factor and 0.593 for gain, while surface model shows GDM values of 0.179 for antenna factor and 0.717 for gain.
Validation results of DRGH antenna are generally less satisfying than those of STLP antenna, both surface and scan model show relatively high values of GDM for antenna factor, that is 0.372 and 0.310 respectively, whereas the values of GDM for gain are as high as 1.260 and 1.350.
For STLP antenna, both models, surface and volume, show relatively similar results, although the simulation parameters are much more favourable for surface model, where simulation time and the memory requirements are almost 20-times lower.

The STLP program is open to all students in all grade levels in every school in Kentucky, and it encourages activities across grade levels and geographies.
Harrison says that students who don't seem to thrive in conventional classrooms often flourish in the STLP environment.
"Students who aren't necessarily the sports stars or might not be involved in other, mainstream school activities come to STLP and find that just about everyone wants to do things with technology, which opens up an avenue for those students to excel."
Harrison says there are active STLP programs in roughly 900 of Kentucky's 1,200 K-12 schools.
According to Lisa Brewer-Mills, STLP School Coordinator at Tyner and Technology Resource Teacher with the Jackson County Kentucky Public Schools, the program is highly successful at motivating the interest of fourth and fifth graders to develop technical and communication skills.
STLP is a project-based learning program that empowers students in all grade levels to use technology.
