and offers a nu mbe r of diff eren t sol ve rs for differe nt types of appl ica tion. Sin ce no meth od wo rks equally well in all application domains, the software contains four different simulation techniques (transient solver, frequency domain solver, integral equation solver, eigenmode solver) to best fit their particular applications. The most flexible tool is the transient solver, which can obtain the entire broadband frequency behaviour of the simulated device from only one calculation run (in contrast to th e fr eq uen cy ste p app roa ch of ma ny othe r si m ul ato rs). It is base d on the Fini te Integration Technique (FIT) introduced in electrodynamics more than three decades ago.

In general Microstrip patch antennas are also known as “PRINTED ANTENNAS ”. Operates on microwave frequencies ( f 1GHz). Invented by Bob Munson in 1972. Became popular starting in the 1970s 4. Basically, the Microstrip Patch Antenna consists of: Metal “Patch”. Dielectric Substrate. Ground Plane.
Antenna Patch Dielectric substrate Ground plane 5. The patch can take different shapes, such as rectangular, circular, triangular, or U-shaped, E-shaped, etc. 6.
Advantages of Microstrip Antennas: Easy to fabricate. Low cost, Less size. Can be integrated with microwave circuits. Easy to feed (coaxial cable, microstrip line, etc.).
Easy to use in an array. 7. Disadvantages of Microstrip Antennas Low gain. Low efficiency.
Narrow bandwidth. 8. Applications in mobile satellite communication system. Wireless LAN’S. GPS system. 9.
Feedings Microstrip patch antenna feeds with different mechanism feedings, the four most popular are:- Coaxial Cable 10. Microstrip Line quarter-wavelength feed inset-fed 11. Aperture coupled (slot) Feed Proximity coupled Feed 12. 13. 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).14. There are a a lot of methods for analysis microstrip patch antenna: The Transmission Line model. The Cavity model. Method of Moments (MoM). The Transmission Line model is the easiest of all 15. The Transmission Line equations To Find Width (W) To find the effective dielectric constant To find the effective length To find the fringing length (∆L) To find the actual length L and the width and length of the Ground 𝐿 𝑔 = 2 ∗ 𝐿 𝑊𝑔 = 2 ∗ 𝑊16.
To design the microstrip feed line (inset-fed) The input impedance is usually 50 Ω. The width of Microstrip feed line (Wf).
The length of inset (Fi) the gap between the patch and the inset-fed (Gpf) usualy 1 mm. 17. 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.
18. To calculate the W, L of the patch by using the equations:- C = 299792458 or 3. 10^8 m/se f˳ = 2.4 GHz or 2.4.10^9 Hz FR4 ► εr = 4.3, h=1.6 mm, t= 0.035 mm W≈ 38 mm, L≈ 29 mm, Fi≈8.85 mm 𝐿 𝑔 = 2 ∗ 𝐿 𝑊𝑔 = 2 ∗ 𝑊 19.
