Array Antennas Yagi-Uda antenna, Micro strip patch array, Aperture array, Slotted wave guide array Used for very high gain applications, mostly when needs to control the radiation patternLet us discuss the above-mentioned types of antennas in detail, in the coming chapters.Print...
This paper presents a 2D FDTD simulation to study operation of GPR using two different types of antenna: antenna array (as in the Reflexw software ) and the dipole antenna (as in GprMax2D) under the same condition. The obtained results show that the array antenna is very useful for GPR ...
In this section, we'll introduce the fundamental antenna types. Almost every antenna in the world can be understood as some combination or derivative of the antennas listed on this page. We'll start with the simplest of all antennas, the short dipole antenna (which is basically a short wire...
The antenna is a communication, used to transmit & receive signals to represent some information. The first antenna was invented by Germans in the year 1888 and used forwireless communicationpurposes. These antennas can broadcast both microwave & radio signals. There are differenttypes of antennasava...
An antenna or aerial in radio engineering is a specializedtransducer, designed by an array of conductors which are connected electrically to the transmitter or receiver. The main function of an antenna is to transmit & receive radio waves equally within all horizontal directions Antennas are available...
Due to evolution of the AAS, which has antenna integrated, initially led to the AAS specification which had both a conducted interface and an OTA (over the air) interface, this was then enhanced to provide an OTA only set of requirements, this has led to 2 types of AAS and corresponding...
It also has many of the features you'd find in a typical laptop computer: a WiFi card, a Bluetooth antenna, a dual-core processor, 1 gigabyte (GB) of RAM and a 64-GB solid-state hard drive. It also has a DVD drive and an integrated Web camera. It comes with the Windows Vista ...
Stepper motor is a type of brushless DC electric motor, stepper motors provide precise position and speed control, without the need for feedback devices to sense position.

Cellphones of the past came equipped with rechargeable nickel-based batteries with (Ni-Cd and NiMH). In the past few years, however, most rechargeable batteries used in phones are Lithium-based. They are either Lithium-ion (Li-Ion) and Lithium Polymer (Li-Po). The fundamental difference ...
