Microsatellites (10–100 kg), nano-satellites (1–10 kg),
pico-satellites (0.1–1 kg).
Compact microstrip antennas are ideal for small satellites.
Desirable at ultra high frequencies and higher frequencies.
It provide a method of increasing antenna performance.

PERFORMANCE ANALYSIS
Performance was first investigated by the EM simulator HFSS 15.
The measurements were carried out using Agilent N5227A network
analyzer.
The impedance and AR bandwidth are sufficient to
cover the HORYU-IV S-band communication requirement.
