Patch Antenna Figure 3

Patch Antenna Structures

Patch Antenna Figure 1

Ozen Engineering co-authored with Averatek Corporation this technical paper on patch antenna structures within printed circuit boards with embedded air dielectrics for improved efficiency and directivity.

For this work, we selected two target carrier frequencies: (i) 2.4 GHz (Bluetooth and WiFi) and (ii) 5.5 GHz (WiFi). At each frequency we designed three models, for six total antennas. At a given frequency, one antenna was a baseline model with a PCB laminate dielectric between the patch and the ground plane, the same laminate used for overall construction.

For the two experimental antennas at a given frequency, we replaced the dielectric with an air pocket in the shape of a rectangular parallelepiped (box). We began with the constraint that the height of a cavity would be the same as the dielectric that it replaced in the baseline unit. Keeping the internal height as a constant, we arrived at patches and overall antenna lateral dimensions that targeted the two carrier frequencies. The difference between the two experimental antennas at a given frequency was this: for one of those antennas, the air cavity was the same lateral size as the patch, and for the other model the air cavity was larger in extent than the patch, roughly 18 – 40% greater in a particular direction.

Miniaturized IOT Antenna Figure 4

Miniaturized IOT Antennas – What is the Size Limitation?

Miniaturized IOT Antennas

Nowadays, wireless communication devices such as IOT place extreme requirements on efficient, miniaturized, and wideband antennas. The antenna designer is faced with the challenging question of whether he could design an antenna to meet these specifications in such limited space. Early in a design cycle it is important to determine if the physical volume specified is, in theory, large enough to allow the design of any antenna which can meet the impedance bandwidth and efficiency requirements.

There is a practical limit to the bandwidth and radiation efficiency of electrically small antennas. Knowing these physical bounds, will help IOT antenna designer prevent diverting resources to solve insurmountable problem. Physical bounds provide information about the maximum achievable performance of antennas. Bounds are derived, in general, independently of antenna geometry, material, and type.

There are well established miniaturization techniques for antenna design . These techniques use antenna dielectric and lumped element loading, introduction of ground plane and short circuits and geometry optimization. These techniques can also be combined to further minimize the antenna size.

James Webb Space Telescope

Engineering the James Webb Space Telescope

James Webb Space Telescope

On December 18, 2021, NASA will launch the James Webb Space Telescope from the ESA launch Facility in Kourou French Guiana.

(To learn more about the James Webb Space Telescope and its mission, see the information and video from NASA below.)

Part of the engineering that has gone into the telescope design was performed by Abed Khaskia of Mallet Technology, a sister company to Ozen Engineering, using Ansys simulation software. This work involved the interactive magnetic/structural simulation of a MEMS micro-shutter.

Additional engineering efforts were performed using Ansys engineering software. Specifically, the powerful matrix manipulation features of the ANSYS Mechanical APDL (Ansys Parametric Design Language) was put to good use.

Other Ansys efforts include a parametric finite-element model for evaluating segmented mirrors with discrete, edgewise connectivity.

According to NASA, the James Webb Space Telescope’s revolutionary technology will study every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe. Webb’s infrared telescope will explore a wide range of science questions to help us understand the origins of the universe and our place in it.

Seeking Light from the First Galaxies in the Universe
Webb will directly observe a part of space and time never seen before. Webb will gaze into the epoch when the very first stars and galaxies formed, over 13.5 billion years ago. Ultraviolet and visible light emitted by the very first luminous objects has been stretched or “redshifted” by the universe’s continual expansion and arrives today as infrared light. Webb is designed to “see” this infrared light with unprecedented resolution and sensitivity.

Exploring Distant Worlds and the Solar System
Webb will also be a powerful tool for studying the nearby universe. Scientists will use Webb to study planets and other bodies in our solar system to determine their origin and evolution and compare
them with exoplanets, planets that orbit other stars. Webb will also observe exoplanets located in their stars’ habitable zones, the regions where a planet could harbor liquid water on its surface, and can determine if and where signatures of habitability may be present. Using a technique called transmission spectroscopy, the observatory will examine starlight filtered through planetary atmospheres to learn about their chemical compositions.
