Abstract :
The paper describes the study of possibility to improve the bandwidth of the LTCC (Low Temperature Cofired Ceramics) antennas. It is well-known that bandwidth broadening of microstrip antennas can be achieved by substrate structurizing. In our paper we describe the influence of an air cavity beneath a radiating patch or strip on the LTCC antenna performance. Results of computer simulations using HFSS™ software are shown. Then, manufacturing process is described. Results of measurement of network parameters and radiaton patterns of the antenna model are presented. Finally, a comparison between measured parameters and computer simulations is discussed.
