Why can't I use antenna array designer to make a line array with LPDA as elements? There is that option, but I can't use it

Hi Qin,

It seems that antennas which are greyed out in the “Antenna Array Designer App” like LPDA are edge-fed antennas for which arrays are not supported and hence is disabled.

As an alternative, you may try utilizing “Conformal Array” to design a LPDA Antenna Array as follows:

ca = conformalArray; 
ant = lpda; 
ca.Element{1} = ant; 
ca.Element{2} = ant; 
show(ca);
