An innovative fabrication technique to create nominal height liquid foam substrate layer for integratable antennas is introduced.The liquid foam layer is intended to replace a Rohacell foam or air substrate, especially at millimeter‐wave frequencies, where antenna designs require substrate layers less than a millimeter thick. The performance of hi‐lo stacked patch antenna with 0.5‐mm‐thick layer of ECCOSTOCK FPH is presented. The 10‐dB return loss bandwidth of the antenna is 18.2%, and the radiation patterns and gain are also presented and discussed. © 2011 Wiley Periodicals, Inc.
