Stacked Microstrip Patch Antenna Research Articles

Simple circuit model for coax-fed stacked rectangular microstrip patch antenna

A simple cavity model for a coax-fed stacked dual-patch electromagnetic-coupled microstrip antenna is presented. It is based on the cavity method and the reaction theorem, and leads to the expression of the input impedance as a function of antenna parameters and of frequency. The theoretical results agree quite well with the data of a full-wave analysis and are close enough to the experimental data. A fast computer program has been implemented on a PC.

Design of wide-band aperture-stacked patch microstrip antennas

A variation of the aperture-coupled stacked patch microstrip antenna is presented, which greatly enhances its bandwidth. Bandwidths of up to one octave have been achieved. The impedance behavior of this antenna is compared with that of other wide-band microstrip radiators. Matching techniques for the antenna are presented and their relative merits discussed. The effects of varying several key physical parameters of the antenna are investigated, lending some insight into its wide-band operation. Variations on the design such as incorporation of additional patches are also discussed.

Wideband aperture coupled stacked patch antennausing thick substrates

An aperture coupled stacked patch microstrip antenna is presented which is capable of operating over a bandwidth in excess of 50%. Measured and predicted impedance behaviour and gain over the band are given. Other important factors such as surface wave efficiency and back radiation levels are presented.

Study of stacked microstrip phased arrays

AbstractA study of phased arrays of rectangular stacked microstrip patch antennas is presented. Two theoretical methods are discussed, i. e., a finite array theory and an infinite array theory. Both theories give almost the same results for a 7 × 7 array, except for edge array elements and for large scan angles. Measured coupling coefficients of a 7 × 7 array are compared with calculations and agree fairly well. © 1993 John Wiley & Sons, Inc.
