The helix antenna is an antenna which fulfill requirement for the low orbit satellite, I,e the pattern radiation of the antenna<br />

should be uni directional <strong>and</strong> if frequencies of communication of satellite are less than 1 GHz the radiation should be circular polarized.<br />

This paper describes how to design <strong>and</strong> producing the helix antenna that fulfill the above requirement. Besides, the computation<br />

of maximum gain, input impedance <strong>and</strong> half beam width are also describe.<br />

The Electronics <strong>and</strong> Electrical Engineering Laboratory (EEEL) promotes U.S. economic growth by providing measurement<br />

capability of high impact focused primarily on the critical needs of the U.S. electronics <strong>and</strong> electrical industries, <strong>and</strong> their customers<br />

<strong>and</strong> suppliers. This measurement capability promotes economic growth by improving the competitiveness of U.S. This capability<br />

is part of the national infrastructure that helps attract <strong>and</strong> retain businesses <strong>and</strong> jobs in the USA. EEEL focuses on<br />

measurement capability that U.S. industries need but cannot provide for themselves, for technical, economic, or other reasons.<br />

The beneficiaries include U.S. industry, government, academia, other organizations, <strong>and</strong> the general public.<br />

The performance of radio frequency (RF) integrated circuits will strongly influence the versatility <strong>and</strong> portability of future<br />

wireless communication systems. With the ever increasing dem<strong>and</strong>s for higher b<strong>and</strong>-width <strong>and</strong> capacity as well as reductions in<br />

size weight <strong>and</strong> cost, the need for more robust <strong>and</strong> efficient RF circuits is expected to increase. Currently, millimeter-wave monolithic<br />

ICs (MMICs) chip sets are under development in the 24-94 GHz range <strong>and</strong> will represent the platform for the RF components<br />

of most wireless systems. With the recent advent of micro-electro-mechanical (MEM) systems, new potentials are being discovered<br />

for applications in the RF/millimeter wave ranges. Each of the MEM classes has produced compelling examples of working<br />

devices such as the tunable micromachined transmission line in the RF-extrinsic class, the shunt electrostatic microswitch capacitors<br />

in the RF-intrinsic class, <strong>and</strong> the capacitively coupled micromechanical resonator in the RF-reactive class.<br />
