Abstract
AbstractThis work presents an experimental investigation of the properties of microstrip patch antennas on bismuth niobate ceramic substrates. The substrate fabrication process and characterization are described. Several prototypes were built and measured for wireless communication systems. A good agreement was observed between measured and simulated results. The very high electrical permittivity of the ceramic substrate provided a reduction of the antenna dimensions. © 2010 Wiley Periodicals, Inc.

Highlights
With many applications on modern communication systems, wireless equipments are almost indispensable
One of the available techniques to minimize the antenna size is the use of ceramic materials with very high permittivity
The purpose of this work is to prepare ultrafine vanadiumdoped antiferroelectric bismuth niobate (BiNbO4) powders using coprecipitation technique, from water-soluble salts, and sintering ceramic rods to application as substrate on development of wireless communication devices and circuits
Summary
With many applications on modern communication systems, wireless equipments are almost indispensable. One of the most important technological challenges is the development of faster, smaller, and multifunctional terminal equipments. Because of the mobility of the wireless communication users, the bottom of line is the development of small-size antennas and devices that are able to handle the defined system requirements. The miniaturization of electronics systems requires smaller antennas. A very good characterization of the antennas is needed. One of the available techniques to minimize the antenna size is the use of ceramic materials with very high permittivity. One of the advantages of ceramic materials over other dielectric materials is the possibility of fabricating compact and easy to build several microwave integrated circuits, such as microstrip patch antennas [1, 2]
