IET Digital Library: Dual-band slot-loaded patch antenna

the use of two sectorial slots on a circular patch [5], a pair of bent slots on a triangular patch [6], a pair of toothbrush-shaped slots on a rectangular patch [7], a pair of dual-bent slots on a rectangular patch [8] and so on. We propose in this article another promising slot-loaded circular microstrip antenna with Dual Polarized Stub Loaded Compact Microstrip Antennas microstrip antenna. The dual band microstrip antenna is obtained by placing open circuit stub on the edges of the patch. The dual polarized operation is realized when these two modes are orthogonal to each other. In this paper, dual band and dual polarized stub loaded C-shaped and shorted L-shaped shaped microstrip antenna are proposed. US8085203B1 - Ground surrounded non-resonant slot-like FIG. 3 shows grounding connections of the patch antenna at two locations along the zero-field line on the patch. FIG. 4 shows the current invention which is a one piece metal which forms the radiator and ground plane. FIG. 5 shows the cross section 19 a of ground surrounded non-resonant slot-like patch antenna in FIG. 4.
