2019 : ANTENNA BASED PROJECTS
2018-2019 Antenna Based Projects for ECE
The dielectric loading of a microstrip antenna affects both its radiation pattern and impedance bandwidth. As the dielectric constant of the substrate increases, ANTENNA BASED PROJECTS for ECEthe antenna bandwidth decreases which increases the Q factor of the antenna and therefore decreases the impedance bandwidth. This relationship did not immediately follow when using the transmission line model of the antenna

Another type of patch antenna is the planar inverted-F antenna (PIFA). The PIFA is common in cellular phones (mobile phones) with built-in antennas.ANTENNA BASED PROJECTS for ECEThe antenna is resonant at a quarter-wavelength (thus reducing the required space needed on the phone), and also typically has good SAR properties. This antenna resembles an inverted F, which explains the PIFA name. The PIFA is popular because it has a low profile and an omnidirectional pattern.
2018-2019 Antenna Based Mini Projects for ECE
The half-wave rectangular microstrip antenna has a virtual shorting plane along its center. This may be replaced with a physical shorting plane to create a quarter-wavelength microstrip antenna. This is sometimes called a half-patch. The antenna only has a single radiation edge (equivalent slot) which lowers the directivity/gain of the antenna. The impedance bandwidth is slightly lower than a half-wavelength full patch as the coupling between radiating edges has been eliminated.
2018-2019 Antenna Based Major Projects for ECE
Microstrip antennas have become very popular in recent decades due to their thin planar profile which can be incorporated into the surfaces of consumer products, aircraft and missiles;ANTENNA BASED PROJECTS for ECE their ease of fabrication using printed circuit techniques; the ease of integrating the antenna on the same board with the rest of the circuit, and the possibility of adding active devices such as microwave integrated circuits to the antenna itself to make active antennas.

Challenges in 5G implementation
Now with 5G, operators are expecting to deliver high-bandwidth with low latency technologies implemented in applications to satisfy various use cases as per the business need. In the wake of 5G rollout, operators go through several challenges as listed below: Spectrum bands are auctioned and wireless carriers need to bid for higher spectrum bands to build their proposed use case and involves huge investment in purchasing desired frequency bands for 5G services. The multi-modal environment will apply millimeter wave (5G mmwave) wireless connectivity in urban areas where population density and data make short-range, high-bandwidth solution optimal. Though 5G frequency is a bit higher and enables increased speed Radio frequency (RF) waves above 28 GHz having their own pros as higher frequencies are more immune to interference and able to carry 1000 times more data compared to spectrum ranges currently deployed for previous generation networks. It has cons too attached being unable to propagate nearly as far, and through obstacles like buildings nearly. Mmwave propagation leads to higher path loss, because of higher frequencies with weaker non-line of sight paths and increase in effect of blockage. 5G small cell antennas are being used to fix and relay signals around obstacles and are distributed in a much more denser way than present cell phone towers. These small arrays will require to be a bit more compact and non-obstructive such as installations made on top of street lights. Additionally, MIMO functionality needs various antennas to be synchronized on a device on the same frequency bands.
