Abstract

Arrangements of compact broadband microstrip antennas are disclosed, Each arrangement comprises a dielectric material (32, 62) with the microstrip mounted to one side and a ground surface (GP) on the opposite side. A first arrangement comprises a closed array of antenna elements (63-70) electrically driven out of phase from one another to excite one or more spiral modes. A second arrangement comprises one or more antenna elements arranged on a magnetic substrate (73) which has a relative permittivity approximately equal to its relative permeability. In a third arrangement, the microstrip antenna operates in a single mode and radiation from other modes is suppressed by varying the spacing above the ground plane (GP) in the radiation zones so that only radiation in the desired zones is fostered. In a fourth arrangement, a spiral mode antenna element (21) is spaced between 1/60 and 1/2 wavelenghts from the ground surface (GP) throughout a multioctave operating frequency range.
The substrate (32) has .epsilon.r ~ 1.0 and the antenna is driven by a near-perfect impedance-matched feed network.
