What is E patch antenna?
An ‘E’ patch antenna is designed and analyzed. The antenna is designed to function in multiple bands in the frequency range of 1-4 GHz depending on the geometric specifications of antenna. It covers applications including GSM 1800, P-GSM, E-GSM, GSM-R, GPS, UMTS and Wi-MAX.
What are the shapes used for microstrip patch antenna why?
The microstrip patch antenna can have any shape but, rectangular, circular, triangular and elliptical are some common shapes. The radiating patch and the feed lines are usually photo- etched on the dielectric substrate. In this paper, four different substrate materials are taken for designing the MSPA.
What do you mean by antenna array?
An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves.
Why do we use antenna arrays?
An antenna array is used to increase overall gain, provide diversity reception, cancel out interference, maneuver the array in a particular direction, gage the direction of arrival of incoming signals, and to maximize the Signal to Interference plus Noise Ratio (SINR).
What is the need of array element antenna?
What is rectangular patch antenna?
A rectangular micros trip patch antenna is a form of antenna which consists of a rectangular patch. This patch is of any planar or non-planar geometry on one side of dielectric substrate and a ground plane on the other side.
How do antenna arrays work?
An antenna array is a radiating system, which consists of individual radiators and elements. Each of this radiator, while functioning has its own induction field. The elements are placed so closely that each one lies in the neighbouring one’s induction field.
What is meant by a broadside array?
A broadside array is a one or two dimensional array in which the direction of radiation (main lobe) of the radio waves is perpendicular to the plane of the antennas. To radiate perpendicularly, the antennas must be fed in phase.
What are the types of array in antenna?
When the signals are counter phase, they cancel each other. The three types of phased array antennas are 1) linear array, 2) planar array, and 3) frequency scanning array.
