A circularly polarized (CP) patch antenna loaded with a metasurface, which is realized with a lattice of 4 × 4 square solar cells, is presented. The antenna is composed of a slotted circular patch sandwiched between the metasurface and the ground plane. This arrangement not only allows for total exposure of the solar cells to sunlight (100% insolation) but also improves antenna performance greatly...
A compact X-band active integrated antenna (AIA) for microwave power transmission with a amplifier on a multilayer substrate was fabricated. The amplifier with a GaAs monolithic microwave integrated circuit (MMIC) in an RF via package was integrated in the antenna. A copper plate for ground and heat dissipation was sandwiched between the substrate. The far-field measurement confirmed a equivalent...
An E-band aperture coupled patch antenna using a combination of GaAs and liquid crystal polymer (LCP) substrates packaged with a laminated multi-chip module (MCM-L) process is presented in this paper. The antenna offers an electromagnetic interface between a GaAs MMIC and a separate dielectric antenna package. Design, manufacture, packaging and test results of the proposed antenna are presented. Measurement...
