Design of Compact Microstrip Patch Antenna for K Band and KU Band Applications

A slotted circular shaped patch antenna with microstrip line feed is printed on FR4(Field Retardant material) epoxy substrate which has a constant dielectric 4.4. The designed antenna covers a bandwidth of (13.6-27.2GHz) having three resonance frequency with perfect return loss (VSWR ≤2) and maximum gain of 2.28dBi. The proposed antenna is being simulated by HFSS(High Frequency Structural Simulator) in which we get good return loss, VSWR, radiation pattern, gain and surface current of the antenna. Moreover the antenna can be used in K band and KU band communications along with other communication channels such as C band (4-8GHz), X band (8-12GHz),Wi-Fi, WLAN, WiMAX, and MVDDS wireless communication systems.
