1. An aperture antenna assembly of a multiphase flowmeter to measure properties of a fluid in a vessel, the aperture antenna assembly comprising:
at least one radiating element to transmit or receive an electromagnetic signal along at least one measurement plane orthogonal to a direction of flow of the fluid in the vessel;
a pressure retaining member to prevent the fluid from entering the aperture antenna assembly through a measurement window of the aperture antenna assembly, wherein at least a portion of the pressure retaining member separates the radiating element and the fluid, wherein the pressure retaining member includes at least one of a low-loss dielectric material or a substantially high dielectric constant material; and
a metal housing, the pressure retaining member being at least partially within the metal housing, the radiating element being coupled to the metal housing.
