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);
Please find below the related documentation links for your reference:
