Slotted Waveguide

Radars demand low profile and light weight antenna subsystems. Microstrip antennas possess these characteristics and serve as an alternative to the bulky and heavy weight reflector/slotted waveguide array antennas, thus an ideal choice for radars. Here, a single line fed microstrip antenna with pierced corners is designed. This antenna has improved parameters compared to the conventional square microstrip antenna. The main problem encountered is in designing the patch antenna with optimum values for various antenna parameters. In order to solve this problem, an alternative solution used is Artificial Neural Networks (ANN). The antenna is also optimized using Particle Swarm Optimization (PSO). The parameters considered in all the cases are return loss (S11) and VSWR which was designed using FEKO software. The designed antennas are found to radiate in the C-band, which covers frequencies in the range 5-8GHz, applicable in most of the modern radars. The simulation design is carried out using CADFEKO suite.

This paper presents the design of a dual-band microstrip patch antenna for Wi-Fi that operates at 2.5 GHz and 5.8 GHz. The antenna contains a rectangular patch with two rectangular slots. The first slot is incorporated in the patch while the second slot is incorporated in the ground plane. The antenna is based on a microstrip fed rectangular patch printed on the FR-4 epoxy substrate with a dielectric constant of 4.4 and a thickness of 1.6 mm with patch size 24 mm × 21 mm. The simulated result shows that the realized antenna successfully works on dual-band and subsequently achieves a bandwidth of 100 MHz and 200 MHz as well as the return loss about -29.9 dB and -15.16 dB for 2.5 GHz and 5.8 GHz respectively. A stable omnidirectional radiation pattern is observed in the operating frequency bands. The antenna meets the required specifications for 802.11 WLAN standards.

Rectangular Microstrip Patch Antenna

This paper presents the design and simulation of a rectangular microstrip patch antenna with enhanced results. Antennas are playing the most important key role in wireless communication systems and especially microstrip patch antenna is the simplest and best form for mobile communication systems. Therefore, the design of antenna for mobile satellite communication and space to earth communication is described in this proposed work. The working of rectangular micro strip patch antenna is studied and the effect of height of the substrate on antenna performance is analyzed and the results are plotted. It has been noticed that the height of substrate should be neither small nor large. The effect of inserting a slot in the patch is also observed in this paper. Return Loss results are plotted for the designed structure and it is noticed that return loss is almost doubled by inserting a slot. Further two symmetrical slots are inserted in the patch and the respective results are plotted. Insertion of two slots gave multiple operating frequencies to the antenna with a compromise of s11. The simulation of proposed structures of antennas is done using ANSYS HFSS (high-frequency structure simulator) which is commercially used as a finite element method solver for electromagnetic structures. A sphere with human brain characteristics is created and average SAR (specific absorption ratio) is plotted on the head model. The proposed antenna has enhanced return loss of -52dB and VSWR of 1.005 at 2.24GHz. This work also introduces multiple operating frequencies using two slots of same size.
