Abstract:
Antennas are fundamental to every form of wireless communication system. Antenna placement is crucial for successful wireless communication, according to satellites and transmitters. So, to enable the use of IoT for remote antenna deployment, this paper provides an IoT-based antenna placement solution. In this case, this paper examines the transmitted orientation of each antenna over the Internet of Things using a sensor-based system that includes a motor on each antenna. When a satellite's or transmitting station's orientation changes, it is necessary to reposition the antenna. The receiving

Reviewing microstrip antennas for diverse applications is the goal of this paper. The designing of microstrip patch antennae is a new study subject established for utilise in 5th generation communications applications. An antenna is a group of interconnected devices that work together to transmit and receive radio waves as a single antenna. Antennas come in many sizes and shapes. An antenna design that is low profile, lightweight, and results-oriented is the microstrip patch.

GPS has become an attractive feature for geolocalization enabling asset tracking IoT devices. GPS satellite antennas radiate RHCP (right-hand circularly polarized) electromagnetic waves; thus, the typical antenna at the receiver is also RHCP. However, when the orientation of the receiving device is random, linear polarization antennas operate better in terms of TTFF (time to first fix). Through field measurements (urban and field) and considering different positions of the device in a vehicle, an RHCP microstrip patch antenna and a linear non-resonant antenna element called an antenna booster

Abstract:
Polarisation diversity is a technique to improve the quality of mobile communications, but its reliability is suboptimal because it depends on the mobile channel and the antenna orientations at both ends of the mobile link. A method to optimise the reliability is established by minimising the dependency on antenna orientations. While the mobile base station can have fixed antenna orientation, the mobile terminal is typically a handheld device with random orientations. This means orientation invariance needs to be established at the receiver in the downlink, and at the transmitter in the upl

In remote areas without conventional cellular service, satellite communication is often the only viable option. Handheld devices for use with satellite communication networks require a high transmit power to obtain a reliable signal. The need for a high transmit power makes it difficult for the device to meet specific absorption rate (SAR) restrictions. An adaptive beam forming technique for shaping radiation away from the user’s head is proposed. This technique uses a back-to-back patch antenna design with an impedance monitoring based system capable of adaptively controlling the pattern of t
