The fractal-like antenna with a total dimension of 62× 89.6 × 0.78 mm3, is fed by a microstrip line placed at the centre axes of the dielectric substrate as shown in Figure 3. Figure 3. Triple band fractal-like antenna with % = 1.25.

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]. This thesis focuses on the aperture coupled patch antenna due to the lack of fabrication and tuning documentation Design procedure of a U-slot patch antenna array for 60 ... Design procedure of a U-slot patch antenna array for 60 GHz MIMO application Abstract: In this paper, we present an antenna array with beam steering capability to characterize MIMO channels over 57-63 GHz frequency band. This uniform linear array is built of six U-slot patch elements which are spaced half wavelength to maximize the beam ... Slot Antenna
Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear.
Non-Resonant Slotted Waveguide Antenna Design Method ANTENNA DESIGN I n this paper a non-resonant slotted waveguide antenna design method is present-ed. The internal and external mutual coupling between adjacent radiat-ing slots is considered in the described meth-od. In order to confirm the usefulness of this method, a non-resonant waveguide array antenna with longitudinal slots cut in a broad
