A 2×2 multilayer parasitic microstrip array antenna (MPMAA) worked at 9 GHz is presented. A parallel side feed system has been used for the first layer, and an impedance match network is used for the antenna to match the coaxial transmission line feed. Coupling feed system has been used for the second and third layers. Prototype of the proposed antenna has been constructed and tested based on the...
In this paper, a dual-layer micro-strip antenna worked at 1.268GHz was designed and analyzed. High and low stacked patches, dual-layer dielectric materials and probe-fed structure were introduced into the design of the antenna. The high patch was used as the incentive patch, and the low patch was used as the coupled patch. Prototype of the antenna had been constructed and tested based on the calculated...
A multiband microstrip patch antenna worked at BD(1.268GHz),GPS(1.575GHz), GLONASS(1.602GHz) is designed by LTCC technology. A power divider matching network printed on the back with LTCC technology is used for the antenna to match the impedance. Prototype of the proposed antenna has been constructed and tested based on the calculated results of HFSS. The test results show that the antenna has a matching...
A small size broadband microstrip patch antenna for 14.0GHz radar application with multiple substrates had been fabricated using LTCC technology. A combination of a relatively low dielectric constant LTCC substrate and a relatively high dielectric constant LTCC substrate had been incorporated to reduce the effect of trade-off relationship between antenna size and bandwidth. The antenna concept was...
