Printed-circuit antennas include stripline slots, printed-circuit-board dipoles, and microstrip patches. A stripline slot consists of a narrow rectangular slot cut in the top stripline ground plane, with the slot excited by proper positioning of the center conductor below the slot. A linear resonant array of collinear slots … Abstract: In this paper, a compact microstrip patch antenna has a slit associated with the slot at the edge of the radiator which is known as slot antenna for WiMAX application is presented. Instead of semi … the dual band characteristic in a microstrip antenna is embedding a slot in the patch as the structure proposed in [3] in which the radiating patch includes a pair of step-slots. In microstrip antennas, embedded slots can also be used to enhance the impedance bandwidth of a single band antenna. A circular arc slot [4] and a U-shaped slot … • With the microstrip antenna, l/2 is a bit too big for consumer mobile devices • Typically for space and military applications • Easy to design/manufacture, yet very capable – Good value, great for antenna arrays • Scale is better for millimeter wave RF (60+ GHz) Microstrip … The selected microstrip antenna is a dual-fed circular polarized microstrip antenna. The antenna consists of miniaturization square patch and 3dB hybrid coupler.

and flared slot (notch) antennas 16]. The problems associated with microstrip patch radiators, i.e. small frequency bandwidth, high losses and high sensitivity to tolerances, both on dimensional and on material parameters, do not exist for waveguide radiators. This is due to the inherent wide bandwidth characteristics of the latter.

In grote radio-antennes, de opening is belangrijk, maar ook in kleinere als de apertuur gekoppelde microstrip antenne. Het kan een vierkante of ronde vorm hebben en heeft een meervoudige …

This paper presents a linear polarized aperture coupled inverted U-slot patch antenna with small steps at the edges. The proposed design exhibits wideband behavior, acceptable return loss, VSWR, gain, small size, and less complexity. The theoretical analysis is based on the finite element method (FEM). This design has wide bandwidth, good return loss, VSWR, and radiation characteristics by The microstrip antenna was attached to a wooden rod, which was placed on a turntable. The antenna was placed at a height of 120 cm. A sine signal with a frequency of 2.45 GHz and amplitude of 0 dBm was fed to the microstrip antenna from a Rohde & Schwartz SMR-20 signal generator.

Abstract: In this paper, a compact microstrip patch antenna has a slit associated with the slot at the edge of the radiator which is known as slot antenna for WiMAX application is presented. Instead of semi-infinite ground plane, the proposed antenna adopts the partial ground plane.

De apertuur van MIRI is maar liefst 6 meter, terwijl soortgelijke instrumenten vóór de JWST niet verder kwamen dan zo’n 0,85 meter. Deze grote ‘opening’ zorgt ervoor dat een veel hogere resolutie kan worden bereikt en dat de gevoeligheid voor zwakkere objecten groter is dan ooit. Hence aperture coupling can solve back radiation problem. An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as  Jun 7, 2013 Aperture Coupled Microstrip Slot Antenna · 5.5 GHz centre frequency · 50 Ω input impedance · Substrate, ε = 3.2, height = 1.0 mm.
