In general Microstrip patch antennas are also known as “PRINTED ANTENNAS ”. There are few basic things that must be known before designing an antenna in general such as: The frequency range in which the antenna is planed to be be propagating, the size of the antenna, the material, the gain of the antenna and the structure of the antenna. Basically, the Microstrip Patch Antenna consists of: • Metal “Patch” • Dielectric Substrate • Ground Plane The patch can take different shapes, such as rectangular, circular, triangular, or U-shaped, E-shaped, etc. Advantages of Microstrip Antennas: • Easy to fabricate. • Low cost, Less size. • Can be integrated with microwave circuits. This article takes research on a novel design of multiband microstrip patch antenna. The proposed multiband microstrip patch antenna can resonate at 7 unique. Microstrip Patch Antenna − Designing at 2.4 GHz Frequency. Designing For designing of a microstrip patch antenna, we have to select the resonant frequency. • Easy to feed (coaxial cable, microstrip line, etc.). • Easy to use in an array. Disadvantages of Microstrip Antennas • Low gain. • Low efficiency. • Narrow bandwidth.

Applications • in mobile satellite communication system. • Wireless LAN’S. • GPS system. Feedings Microstrip patch antenna feeds with different mechanism feedings, the four most popular are: • Coaxial Cable • Microstrip Line • Aperture coupled (slot) Feed • Proximity coupled Feed To design a Rectangular patch antenna. There are four essential parameters which are important to know: • The operating frequency (f˳). • Dielectric constant of substrate (εr). • The height of the dielectric substrate (h). • The height of the conductor (t). The other parameters: • The width of the patch -W • The length of the patch -L • The width and length of the Ground plane and the substrate -Wg -Lg There are a a lot of methods for analysis microstrip patch antenna: • The Transmission Line model. • The Cavity model. • Method of Moments (MoM) Example: To design a microstrip patch antenna with the microstrip feed line (inset-fed) work on for WiFi 2.4 GHz. • The operating frequency (f˳) = 2.4 GHz. • FR4 material have: • Dielectric constant of substrate (εr) = 4.3. • The height of the dielectric substrate (h) = 1.6 mm. • The height of the conductor (t) = 0.035 mm. The Parameters Microstrip Patch Antenna Design @2.4 GHz with CST Studio Suite. Diagram of the feed structure of a microstrip antenna array. In, a microstrip antenna (also known as a printed antenna) usually means an fabricated using techniques on a (PCB). They are mostly used. An individual microstrip antenna consists of a patch of metal foil of various shapes (a ) on the surface of a PCB, with a metal foil on the other side of the board.
