A microstrip-fed slot antenna was designed using Antenna Magus for the following specifications:
- 5 GHz centre frequency
- 50 Ω input impedance
- FR4 substrate, ε = 4.35, height = 1.5mm
Dimensions of the slot and feed-line are:

In addition, by applying a curve-fit formula, it is possible to locate the exact inset length needed for a 50-Ω input impedance. The feed mechanism plays an important role in the design of microstrip patch antennas. A microstrip patch antenna can be fed either by coaxial probe or by an inset microstrip line.
- Ws = 743.3 μm
- Ls = 18.58 mm
- Wf = 2.892 mm
- Wm = 625.7 μm
- S = 8.053 mm
FEKO’s implementation of the planar Greens function features the ability to model the slot in the ground plane as magnetic triangles, which means that only the slot is meshed and not the ground plane itself, saving significantly on simulation resources.

- Proposed a compact microstrip-fed narrow slot antenna design for UWB applications. By properly loading a notch to the open-ended T-shaped slot and extending a small section to the microstrip feedline, an impedance bandwidth ratio of 3.7:1 (3.1 11.45 GHz) is obtained.
- The antenna is printed on the two sides of a single substrate and has two microstrip feed lines to excite a V-shaped slot formed by the merging of two tilted rectangular step shaped slots. Stepping of the slot sections as well as the feed line improves the impedance matching.
