Journal ArticleDOI
Microstrip patch designs that do not excite surface waves
David R. Jackson,Jeffery T. Williams,A.K. Bhattacharyya,R.L. Smith,S.J. Buchheit,Stuart A. Long +5 more
TL;DR: In this article, two variations of a circular microstrip patch design are presented which excite very little surface wave power and thus have smoother radiation patterns when mounted on finite-size ground planes, due to reduced surface wave diffraction.
Journal ArticleDOI
Characteristics of space and surface waves in a multilayered structure (microstrip antennas)
TL;DR: In this paper, the authors explored the characteristics of space and surface-wave fields produced by an electromagnetic source in a multilayered structure using the integral transformation technique, and showed that the space and the surface wave modes are orthogonal along the longitudinal direction with respect to an appropriate weighting function.
Journal ArticleDOI
Effects of finite ground plane on the radiation characteristics of a circular patch antenna
TL;DR: In this article, an analytical technique to determine the effects of finite ground plane on the radiation characteristics of a microstrip antenna is presented, where the induced currents on the ground plane and on the upper surface of the patch are determined from the discontinuity of the near field produced by the equivalent magnetic current source on the physical aperture of a patch.
Journal ArticleDOI
Effects of ground plane and dielectric truncations on the efficiency of a printed structure
TL;DR: In this paper, the effects of ground plane and/or dielectric truncation on the radiation efficiency of a printed radiator are studied, and a closed-form expression for the reflection coefficient of surface wave modes from the truncated edge is obtained.
Journal ArticleDOI
Long rectangular patch antenna with a single feed
TL;DR: In this article, the authors investigated the radiation characteristics of a single-feed long rectangular patch antenna and derived the complex propagation constant of the traveling wave by solving the wave equation with impedance boundary conditions.
