An impedance modeling for a unit cell of the circular loop and square loop FSS structure is presented in this paper. The unit cell of the circular loop and square loop FSS are designed and simulated using the CST Microwave Studio software at 2.4 GHz based on industrial, scientific and medical bands (ISM). The design FSS structure consists of FSS structures placed on the FR4 and glass. The reflection...

The design FSS structure consists of square Frequency Selective Surface (FSS) structures placed on the FR4 and glass. The circular and square slot is added on the FSS to design and simulate by using the CST Microwave Studio software for 2.4 GHz and 5.2GHz based on industrial, scientific and medical bands (ISM) standard. The reflection (S11) and transmission (S21) of the design FSS structure is analyzed...

Equivalent Circuit (EC) method gives a simple alternative method in FSS analyses which are useful for quickly predicting the characteristic of FSS. Impedance of the EC for a unit cell of the design Frequency Selective Surface (FSS) structure is investigated in this paper. The unit cell of the design FSS structure consists of FSS structures placed on the FR4, glass and hybrid (FR4+glass). The square,...

At present, various switch control system technology is introduced, where a control system plays an important role. In heavy industry, a lot of instrumentation needs to be controlled and this will contribute in increasing wire harness between instrumentation and control terminal. This paper will discuss about an application of wireless communication to minimize the use of wire harness in industries...

The design FSS structure consists of square loop FSS structures placed on the FR4 board and glass. The square loop FSS is designed and simulated by using the CST Microwave Studio software for 2.4 GHz based on industrial, scientific and medical bands (ISM) standard. The reflection (S11) and transmission (S21) of the design FSS structure is analyzed based on the six types of configuration that have...

This paper presented an impedance modeling of the Equivalent Circuit (EC) for a unit cell of the square loop Frequency Selective Surface (FSS) structure. The unit cell of the square loop FSS is designed and simulated using the CST Microwave Studio software at 2.4 GHz based on industrial, scientific and medical bands (ISM) standard. The square loop FSS is simulated without FSS, with square FSS and...

This paper discussed the investigation on the effect of two main parameters of a circular polarized patch antenna by using stub technique. The results show that this technique can improve the performance of return loss and gain result of the patch antenna. The operating frequency of the proposed antenna is 2.4 GHz with 40 MHz of bandwidth and return loss is −40dB. The antenna had been designed and...
