Abstract :
The microstrip patch antennas with high-permittivity ceramic substrate is very effective for antenna size reduction. However, the impedance bandwidth obtained for such a microstrip patch antenna is usually very narrow and the antenna gain is also significantly decreased, and that will severely limit its practical applications. Therefore, the enhancement of the bandwidth and gain of a microstrip patch antenna with high-permittivity substrate is highly desirable. This paper presents a stacked patch antenna structure with enhanced bandwidth and good radiation. Details of the proposed stacked antenna and experimental results are discussed.
