Abstract
The most important parameter for any flying vehicle is altitude. Different techniques and methods are available for altitude measurement; one of these methods is RADAR Altimetry. In this technique altitude measurement of an in-flight vehicle is measured by using RF waves and RADAR. RADAR Altimeter transmits low-power radio waves, these waves incident on the earth and get reflected back with a shift of about 40 Hz/feet. The altitude is determined as per the time delay between the signals which is measured by differentiating the broadcast and received signal for a specific time period. The RADAR altimeter operates on a frequency range of 4.2 to 4.4 GHz in the C-Band. Different shapes of microstrips are tested and used for this application. In this article, a rectangular microstrip antenna is designed and simulated at 4.2GHz and its performance and characteristics are analysed using ANSYS HFSS.
