Microstrip Patch Antenna Ahmed T. Hassan Abstract—The paper represents the design and the simulation of high a high gain 2.4GHz Microstrip Rectangular Patch Antenna for wireless communication applications. Index Terms—Microstrip Patch Antenna, Radiation Pattern, VSWR, S-Parameter I. INTRODUCTION Recently, The Microstrip Patch Antennas became one of the most demanding antenna based as the high demand of antennas for wireless communication systems such as wireless local area network (WLAN), cellular phone, medical applications. and satellite communication. As shown in Fig. 1, The Microstrip Patch Antenna consists of a metallic patch above a ground plane. The shape and size of patch determine the frequency of operation of the antenna and its…

1.1 Overview: In antenna theory of analysis and design, the most forward looking topic is microstrip patch antenna. Microstrip patch antennas are made to have many different geometrical shapes and dimensions but among all the shapes of microstrip patch, four of them are most common than another that are square, rectangular, dipole and circular. They are employed in wide range of modern applications because of their easiness to design and compatibility with printed-circuit technology. The basic…

output (MIMO) System of two U-shape patch antennas has been evolved for the UWB application. Spacing between two elements of antennas is 0.270 at 3.1GHz for the UWB operation. To enhance isolation and increase bandwidth impedance, fork shaped stub added in the ground plane of the antenna. Due to interference of WIMAX (3.3-3.7 GHZ) and WLAN (5.2-5.8 GHz) on UWB dual band notch function is perform. For achieving the dual band notch characteristics, trekking slot cut in the patch with feed and…

receiver. Next, RF transmission is greater than more reliable than IR transmission. RF conversation makes use of a unique frequency unlike IR signals, who are affected, by mean IR emitting sources. This RF module contains an RF Transmitter or an RF Receiver. The transmitter/receiver (Tx/Rx) associate operates at a frequency regarding 434 MHz. An RF transmitter receives serial facts and transmits it wirelessly via RF via its antenna related at pin4. The transmission takes place at the degree…

Polarization in Antenna Polarization is the basic thing used in transmission antennas for the propagation and reception of the signals. As we know that antenna emits electromagnetic waves in the space for the communication purposes. These two types of waves as depicted by the name Electro-Magnetic is a combination of electrical and magnetics fields. These two waves are mutually orthogonal i.e. oriented at an angle of 90o with each other. The general wave form is given as Fig: Electromagnetic…

-It is very practical and is used in Japan in Modern Land Mobile Radio Systems. • Demerits of this model: -It has a slow response for rapid changes in terrain. Thus, it is fairly good in urban and sub urban areas but it is not so good in rural areas. 3. Hata model: • This model is an Empirical Formulation of graphical path loss data that is given by Okumura. • Its frequency range is 150 MHz – 1500 MHz. • Its formulation is limited to only certain ranges of input parameters. • Its formulations…

(D. Tse and P. Viswanath, 2005) In 151, the proposed scheme is known as "the diversity of user cooperation," the author of this particular plan to achieve the rate in the region and the probability of failure. Sendonaris, who proposed a simple method of user cooperation, based on a signal of DF with the CDMA scheme. According to Liu (2009), different users with different orthogonal spreading codes can distinguish between different forms of cooperation from users to send information to the…

Epicurus believes that happiness is the ultimate goal in life. Dr. Hunter “Patch” Adams, played by Robin Williams in Patch Adams, a film about a medical student who suffers from depression, also shares that idea. Although differing in reasons, the philosophies of Dr. Patch Adams ad Epicurus coincide: happiness is obtained through simple pleasures, a life of wisdom is acquired through nonconformity, and death should not be feared. According to both Epicurus and Patch, a life filled with…

The Cabbage Patch Dolls had a large surge of popularity in the 1980s that didn’t last. A man named Xavier Roberts a Georgian sculptor had created them. He used the technique of “needle molding” to create these dolls. First, he had called these dolls “Little People” but later on developed onto what is now known as the “Cabbage Patch Kids”. Xavier Roberts had an art exhibit he would showcase them at. His assistants were then told to dress in maternity clothing and held the dolls up as if they were…
