The suggested system utilizes an inverted F metal zipper to act as an antenna. Here we have proposed an antenna which is designed using HFSS software in order to assure safety of women. The antenna design is carried out in three layers namely Ground plane, substrate and patch. Copper is used as ground and patch and substrate is made of FR4 material. The feeding point is identified at the bottom of the zipper, nearby one of the teeth. Simulations and measurements are made with HFSS. Changes in the radiations styles and the reflections coefficients happens when there is any disturbance in the teeth. The zipper constantly remains closed. The antenna will function even if the zipper is partially opened or closed. The suggested model remains as reconfigurable, particularly for radiation styles and also possess high gain value. The measured values give proper results based on simulations in terms of matching functionalities and radiation properties for the designed zipper, which acts as a good wireless product for women safety. This antenna design can be used in various applications when it is interfaced with some embedded system devices like GPS in order to find the location of the affected person and the material onto which it is going to be placed can also be made flexible that is, it can be used as Zip in dress material, hand bag, or can also be worn as an ornament.

Functional States

In this paper, a printed Yagi antenna with an integrated balun is proposed for CubeSat communications. The printed antenna is mechanically adjustable to realize three functional states at different operating frequencies in the L-band and S-band respectively. Three different angle deployments are proposed at 10°, 50° and 90°, so that the antenna operates at three different operating frequencies, namely 1.3 GHz (L-band), 2.4 GHz (S-band) and 3 GHz (S-band). The measured results of the fabricated antenna are well matched with the simulation, having frequencies of 2.82–3.07 GHz, 1.3–1.4 GHz and 2.38–2.57 GHz, with similar radiation patterns. The measured gain of the antenna is 8.167 dBi at 2.4 GHz, 5.278 dBi at 1.3 GHz and 6.120 dBi at 3 GHz. Keeping within the general theme of cheap off the shelf components for CubeSats, this antenna design allows the CubeSat designers to choose from three popular frequencies, through a simple angle configuration. The main contribution of this work lies with the reconfigurable frequency, relatively high gain and simplicity of design.
