Microstrip Antenna Design with Low Frequency

In this paper, we design patch antenna for high frequency (HF) and very high frequency (VHF). Due to size problems, patch antennas are not suitable for lower frequencies. In order to overcome these problems we try to different approach. First of all, we think a dipol antenna for a certain frequency, in which desired microstrip antenna operate, then we calculate antenna length at a resonance frequency. After, we design antenna with microstrip lines on FR4 with specified length. Finally, some optimizations and simulations are making with the help of Computer Simulation Techonology Microwave Studio.
