What are the features of microstrip antennas?
A Microstrip Antenna in its simplest form consists of a radiating patch on one side of Dielectric substrate and a ground plane on the other side. Most common shapes are rectangular and circular. However, other Shapes such as the square, mendered, triangular, semicircular and annular ring Shapes are also used.
What are the major components of microstrip patch antenna?
The Microstrip Patch Antenna is a single-layer design which consists generally of four parts (patch, ground plane, substrate, and the feeding part).
What is the principle of antenna?
How does an antenna work? The antenna at the transmitter generates the radio wave. A voltage at the desired frequency is applied to the antenna. The voltage across the antenna elements and the current through them create the electric and magnetic waves, respectively.
What is microstrip array antenna?
A microstrip antenna array is one of the simplest forms of antennas available. The antenna consists of a single printed circuit board with an RF connector and perhaps an absorptive load. Microstrip antennas can be flat or curved to suit the structure to which they are mounted.
What is the acceptable value of ECC?
Most often, however, ECC is just evaluated for a uniform isotropic field; something that never happens in the real world! That said, a correlation below about 0.3-0.4 is usually considered “good enough” for MIMO.
What is the frequency range of patch antenna?
Therefore the resultant antenna is a multifrequency antenna ranging from 13-19 GHz. The microstrip rectangular patch antenna was designed for 9GHz however after analysis it resulted in an multifrequency antenna ranging from 13-19GHz . Thus, this antenna can be used in wireless communication with bandwidth 6 GHz.
What are the applications of microstrip antenna?
In global positioning satellite (GPS) systems, circularly polarised microstrip antennae are used. They are very compact in size and quite expensive due to their positioning. Microstrip antennae are also used in the fields of RFID (radio frequency identification), mobile communication and healthcare.
Which parameters do we need to calculate radiation patch width and length?
All Answers (9) The microstrip patch antenna calculator determines the length (L) and width (W) of a rectangular microstrip patch antenna for a given resonant frequency or vice versa. The substrate parameters (εr and h) are required.
What are feeding methods in microstrip antenna?
There are four types of the feeding techniques and they are coaxial probe, microstrip line, aperture coupled and proximity coupled.
What are the parameters of a microstrip patch antenna?
Likewise, microstrip patch antenna is having lots of parameters like VSWR, Gain, Bandwidth, Return loss, Directivity etc. The shape of the microstrip patch also matters to get the different outputs.
What is a micro strip antenna?
Micro strip antenna consists of a very thin metallic strip placed on a ground plane with a di-electric material in-between. The radiating element and feed lines are placed by the process of photo-etching on the di-electric material.
What is alak Majumder’s H shaped microstrip patch antenna design?
Alak Majumder has designed H shaped microstrip patch antenna for bluetooth applications [11]. In this design, FR4 substrate material is used and copper is used as patch materi- al. The antenna resonates at 2.4 GHz. The gain of it is 8.9367 dB and the return loss of it is -22.9 dB.
How do the parameters in rectangular patch antenna design affect performance?
All of the parameters in a rectangular patch antenna design ( L, W, h, permittivity) control the properties of the antenna. As such, this page gives a general idea of how the parameters affect performance, in order to understand the design process. First, the length of the patch L controls the resonant frequency as seen here.
