1. Types of Microstrip Antenna

• Berdasarkan mekanisme pemasok (Inset feed, CPW feed, coupling feed, etc.)
• Berdasarkan bentuk patch (square, circular, hexagonal, fractal, etc.)
• Berdasarkan frekuensi operasi
• Berdasarkan rentang operasi (wideband, multiband, single band, dual, tri band, etc.)

2. Types of Microstrip Antenna

• Micropstrip patch antenna
• Micropstrip dipoles antenna
• Printed slot antenna
• Micropstrip travelling wave antenna

3. Printed Slot Antenna

• Sebuah slot dalam plane dasar yang grounding.
• Bisa memiliki bentuk apa pun.
• Teori, sebagian besar bentuk patch dapat direalisasikan sebagai printed slot.

4. Basic Printed Slot Antennas with Feed Structures

• A. Printed slot antenna fed by microstrip line

• 1. Printed narrow slot antenna
• 2. Printed wide slot antenna
• 3. Printed wide slot antenna generating CP wave

• B. Slot antenna fed by CPW

5. Printed Dipole Antenna

• Dua wire yang berarah sebaliknya, tersusun secara horizontal atau vertikal.

6. Properties of Dipole Antenna

• Ukuran: Tergantung pada frekuensi atau panjang gelombang radio.
• Bentuk: Berbeda dengan ukuran dan rentang operasi.

7. The Dipole Antenna Parameters

• Frekuensi resonansi
• Impedansi
• Gain
• Polarization
• Efficiency
• Bandwidth

8. Common Application of Dipole Antenna

• Set top TV antenna – "Rabbit ears" type used with televisions.
• Folded dipoles – Another common place one can see dipoles are as antennas for the FM band.

9. Micro-strip Travelling Wave Antenna

• Concatenated sections of periodic micro-strip lines or long segments of sufficient bandwidth.
• Support the propagation of transversely electric (TE) waves.
• Terminated by resistive loads.

10. Advantages and Disadvantages of Micro-strip Travelling Wave Antenna

Advantages:

1. Low cost
2. Light weight
3. Easy fabrication

Disadvantages:

1. Limited bandwidth
2. High power consumption

11. Micro-Strip Patch Antenna (MSPA)

• Sebuah patch radiasi pada satu sisi substrat dielektrik dan plane dasar yang grounding.
• MSPAs juga dikenal sebagai "patch antennas" atau "printed antennas" atau "planar antennas".

12. Construction of MSPA

• The normalized radiation pattern:
• The frequency of operation / centre frequency:

13. Advantages of MSPA

1. Low cost
2. Light weight
3. Easy fabrication
4. Linear and circular form
5. Compatible with modular designs
6. Easily mountable on space vehicles, missiles, etc.
