MICROSTRIP ANTENNA AND CASE WITH MICROSTRIP ANTENNA

摘要

PURPOSE:To realize the case with the microstrip antenna of a structure in which the microstrip antenna is integrated as part of the case of a portable communication equipment by realizing the microstrip antenna for the portable communication equipment with a dielectric substance or a composite dielectric substance with economy and light weight having a prescribed specific dielectric constant and excellent processing performance. CONSTITUTION:A dielectric plate 15 whose upper face and lower face formed in parallel is made of a high polymer material having a specific dielectric constant of 5 or over or of a composite material having a prescribed specific dielectric constant of a composite material comprising an inorganic dielectric body having a specific dielectric constant of 5 or over and a high polymer material, and a radiation electrode 16 of a prescribed shape is formed to the upper side and an earth electrode 17 is formed to the lower face respectively as a thin film. The radiation electrode 15 is energized through the feeding point 18 from a throughhole penetrated from both the electrodes 16, 17.
