#	It is ready to be loaded working on MILLIMETER units
#
#	Creates a Jerusalem Cross with predefined sizes designed
#	to work at the design frequency. It may be scaled to adapt it
#	at different frequencies.
#	The following specifications are listed:
#		f: final design frequency (6 GHz, by default)
#		a: central arms size (5.04 mm, by default)
#		b: side arms size (10.4 mm, by default)
#		t1: central arms thickness (1.89 mm, by default)
#		t2: side arms thickness (0.63 mm, by default)
#		fDesign: design frequency
#		scale: factor to adapt the design fro fDesign to f
#	
#	Parameters with fixed values

set f {6.0}# Changes just this parameter to the final frequency (in GHz)

set fDesign {6.0}
set scale  = fDesign/f
set a  = 5.04*scale
set b  = 10.4*scale
set t1  = 1.89*scale
set t2  = 0.63*scale

#	Auxiliary parameters defined automatically

set $3  = -a-t1/2
set $5  = a+t1/2

#	Creates the cross arms with nine rectangular surfaces
#	They are created with the plane command, with the name of resulting objects (-n)
#	and its geometric parameters (-p) (lower X Y Z corner, and X Y Z sizes)
