Abstract: This paper presents improvement of insert feed microstrip antenna with types of types of metamaterials. The antenna and the metamatrials were printed on a thin substrate, Rogers RT5880 with 0.254 mm thickness. Two types of metamaterials were introduced; Artificial Magnetic Conductor (AMC) and Frequency Selective Surface (FSS). The metamaterials were placed on the bottom of the antenna with no gap. Four cases were analyzed; antenna alone, antenna with AMC, antenna with FSS and antenna with multi-layer of FSS-AMC. Performances of the antenna were evaluated in terms of return loss, useful bandwidth and realized gain. The resonating frequency was shifted but still operate well at 28 GHz. Improvements in useful bandwidth from antenna alone and as it worked with all types of metamaterials. The realized gain was effectively improved from 1.76 dB up to 6.16 dB for the fourth cases. The design of insert feed microstrip antenna with types of thin metamaterials can be applied as a flexible applications in advanced sensors.
