“…because the latter radiates and the first removes all unnecessary frequencies, therefore, combining these functions into a single module will eliminate the additional circuit and improve the circuit's overall performance [5]. In this sense, several integrated filters have been proposed [6][7][8], among these filters, hairpin filter is widely used for its simplicity, for example, in [9] a microstrip six-order hairpin band pass filter operating at the X-band frequency was designed by using open stub and Defected Ground Structure (DGS), the substrate used is the Rogers RT5880, which has a loss tangent of 0.0009. In [10] Two third-order hairpin filter designs have been developed for possible applications in the 5G (3.7 GHz-4.2 GHz) and (5.975 GHz-7.125 GHz) low frequency bands.…”

A new compact microstip filtering Diamond Antenna (DA) is presented in this article for possible applications in the Fifth-Generation (5G) at the n77-band (3.3 GHz-4.2 GHz), such as, Fixed Satellite Service (FSS) which is a radiocommunication system between fixed earth stations utilizing one or more satellites. The structure is implemented on an FR4 Epoxy substrate wich has a dielectric constant ϵ r = 4.4, a loss tangent tan(δ) = 0.025 and a thickness h equal to 1.6 mm. The substrate has a small size of 39.7 × 30 × 1.6 mm 3 which make it suitable to be integrated in various intelligent systems. A good results are obtained with this design, starting with the reflection coefficient S 11 which is equal to -22.31 dB at the first resonant frequency 3.57 GHz and -34.41 dB at the second resonant frequency 4.10 GHz. Several other results will be presented and discussed later in this article. The software used for the simulation is High-Frequency Structure Simulator (ANSYS HFSS) which employs the finite element approach. A prototype of the filtenna (filtering Antenna) was fabricated and measured using the Vectorial Network Analyzer 3656D (VNA).

“…Additionally, the microstrip bandpass filter's design can be modified in terms of the number of hairpin structures utilized for the overall design, such structure can use more than five poles and as a consequence, the results obtained by the parametric study are in close proximity of the acceptable range (T. Hariyadi et al, 2018). The proposed geometry can be enhanced by using DGS and minimizing the size of the filter due to the application requirements (T. Hariyadi et al,2018;N.Ismai et al,2018).High performance can be achieved by utilization of microstrip hairpin filters with adjustment in folding the hairpin line and thus reducing the size from 60-65% (Jagdish Shiyhare et al, 2015;S.B.Jain et al, 2012).…”

The paper depicts a microstrip hairpin bandpass filter design, simulation, fabrication and test. The proposed microstrip filter's design is comprised of five hairpin structures separated by a tenth of a mm distance for which various parametric studies have been conducted. The simplicity of design provides inexpensive and undemanding filter. The filter is fabricated with suitable parametric results. The design is based on Chebyshev's values for the prototype, with N (the order of filter) number being equivalent to five. The final fabricated version of the project is based upon FR4 dielectric substrate with the input return loss being below -10 dB and insertion loss above – 2 dB. Approximate values of the input reflection coefficient and insertion loss are -33.34 dB and -1.72 dB respectively. Furthermore, the frequency range for the proposed geometry is between approximately 2.6 GHz and 3.6 GHz. The proposed filter is fabricated and the results measured in real life are highly correlated to the results simulated in the software. The proposed microstrip hairpin bandpass filter can be utilized in wireless internet access and communication.
