This article present a compact proposed patch antenna for impedance matched for simple two horizontal slot is placed in a active patch with a via hole in sandwiched between radiated patch and bottom plane of an microstrip patch antenna for a band of 4 to 12Ghz application. The planned antenna is synthesized by using glass reinforced epoxy laminated material (FR4) and electromagnetic 3D view (IE3D) software. The software based design is suitable for a band of 3.3//5.5 Wi-Max and 5.3/5.8 WLAN frequency band. It is also suitable for satellite application The ground and exciting patch is separated by 1.5mm thickness. The proposed antenna parameter is design for 10Ghz..For such design the achieved Bandwidth for an antenna is 53 % at a VSWR<2, acceptable return loss (S11) = - 22.5dB, and the directivity of an antenna is 6 dBi. The antenna is appropriate for an application of X band. The designs of an antenna and its result have been discussed in detail.

In this paper, a planar multiband microstrip patch antenna is presented for narrow band internet of things (NBIoT) applications. The simple planar structure covers three of the approved bands (830-840 MHz), (850-890 MHz) and (1190-1200 MHz). The return loss at resonance frequencies is less than20dB and radiation pattern is omnidirectional as desired, for all the bands. Simple basic equations of microstrip patch antenna are used for design. The simulation and performance analysis is done using HFSS tool. The design considers simple, easily available printed circuit board (PCB) with FR4 dielectric material between the patch and ground plane. Which is inexpensive, fulfills the basic need of the application. The optimetrics of the HFSS simulation tool are handy, used extensively to find appropriate feed position, optimize return loss, gain and to tune the resonance frequencies.

In this paper, a microstrip patch antenna is designed to be used for X-band VSAT application at 7.5 GHz. The antenna is proposed to replace the massive and commonly used parabolic reflector antennas (46.0 inch × 29.3 inch × 13.5 inch (116.84 cm × 74.42 cm × 34.29 cm) with weight of 66.2 kg) in terms of portability due to its compact and lightweight features, with overall dimensions of 19.00 mm × 30.55 mm. The 7.5 GHz frequency is chosen based on the X-band frequency used in Malaysia, as reported by STRIDE. The microstrip patch antenna is first designed and simulated using CST Microwave Studio (CST MWS) and exhibits a good return loss (S11) of -42.09 dB, a bandwidth of 399 MHz, directivity of 7.63 dB and gain of 7.18 dB. The antenna is then fabricated using RT/duroid ® High Frequency 5880 substrate with a dielectric constant of ?r = 2.2, loss tangent of ? = 0.0009 and thickness of t = 1.574 mm. Next, the return loss and radiation pattern measurements are carried out to confirm the simulated results. The measurement of the antenna prototype provides a return loss S11 of -30.53 dB, bandwidth of 455 MHz, directivity of 5.51 dB and gain of 3.88 dB. ABSTRAK: Di dalam kajian ini, antena jalurmikro dicadangkan untuk tujuan aplikasi jalur-X VSAT pada 7.5 GHz. Antena jalurmikro ini dicadangkan untuk menggantikan antena reflektor parabola yang besar dan biasa digunakan (46.0 inci × 29.3 inci × 13.5 inci (116.84cm × 74.42cm × 34.29cm) dengan berat 66.2kg), kerana cirinya yang mudah alih dengan fizikalnya yang kecil dan ringan, dan dimensi keseluruhan 19.00 mm × 30.55 mm. Frekuensi 7.5 GHz dipilih berdasarkan frekuensi jalur-X yang digunakan di Malaysia, seperti yang dilaporkan oleh STRIDE. Antena jalurmikro ini direka dan disimulasi menggunakan perisian CST Studio Gelombang Mikro (CST MWS) dan menghasilkan kehilangan pulangan yang baik S11 -42.09 dB, lebar jalur 399 MHz, keterarahan 7.63 dB dan gandaan 7.18 dB. Antena jalurmikro ini kemudiannya direalisasikan dengan menggunakan substrat RT / duroid ® Frekuensi Tinggi 5880 dengan pemalar dielektrik ?r = 2.2, tangen kehilangan ? = 0.0009 dan ketebalan t = 1.574 mm. Seterusnya, pengukuran kehilangan pulangan dan corak radiasi dilakukan untuk mengesahkan keputusan simulasi. Pengukuran prototaip antena jalurmikro menunjukkan kehilangan pulangan S11 -30.53 dB, lebar jalur 455 MHz, keterarahan 5.51 dB dan gandaan 3.88 dB.

Abstract: In the present work an attempt has been made to design and simulation of rectangular microstrip patch antenna with triple slot for X band using microstrip feed line techniques. HFSS High frequency simulator is used to analyse the proposed antenna and simulated the result on the return loss, radiation pattern and gain of the proposed antenna. The antenna is able to achieve in the range of 8-12 GHz for return loss of less than -10 dB. The operating frequency of the proposed antenna is 8.4 GHz & 11 GHz with dielectric substrate, ARLON of = 2.5 and h= 1.6mm. Keywords: ARLON substrate material, FEM, Microstrip Feed Line, X band
