A modified microstrip line fed compact UWB antenna for WiMAX ... The antenna consists of a rectangular patch of dimension L p × W p. A tapered microstrip line with annular sector at the top is used which modifies the feed line as spanner shape. The modified spanner shaped microstrip line terminates with rectangular patch whose lower left edge is etched with a rectangular slot of dimensions L p1 × W p1. Microstrip-Fed Dual-Frequency Annular-Slot Antenna Loaded by ... annular-split-ring by a narrow rectangular slot. The slot antenna is fed by a stepped microstrip line, which provides impedance matching. Usually, the resonant frequencies are mainly determined by the circumference length of the annular-slot. For the proposed annular-slot antenna, the first mode is mainly determined by the circumference of Aperture Coupled Microstrip Antenna Design and Analysis Aperture Coupled Microstrip Antenna Design and Analysis Michael Paul Civerolo A linearly-polarized aperture coupled patch antenna design is characterized and optimized using HFSS antenna simulation software [1].
