“…Fig. 7 shows that EMSPOSCP exhibited linearly polorized broadside pattern with 57 o half power beamwidth.The gain is improved to 8.31dB due to the current path excitation resulting into decrease of qfactor of antenna [33]. This antenna has its applications in communication band…”

“…From the Multiple methods of design the novel slot etched patch with direct strip feeding was found to be rare in survey papers and this method proves to enhance various antenna [25][26][27][28][29] parameters. Improving bandwidth, gain and radiation pattern [30][31][32][33][34][35] of MSA has been important research challenge in the strip line antenna field. A compact, circularly polarized wideband (CP) squared slot antenna for universal ultra-high-frequency (UHF) handheld reader (RFID) applications is proposed [36].…”

This paper aims for the design and development of a multi slotted novel patch antenna with multiband characteristics. The work focused on designing a patch, feedline with novel multi-slots on the same patch which can be commonly used in wireless applications. In addition, the analysis shows the effects of the improved antenna properties obtained by etching such novel slots on epoxy dielectric substrate using photolithography process. The paper concentrated on the design aspects of the patch antenna with slot dimensions as a function of operating wavelength (λ) to get better results. The antennas are implemented with the help of software package V15.4 - Integral Three-Dimension Equation (IE3D) EM simulator. The experimental and simulation findings show the overall required bandwidth of 1120MHz with a return loss of -43dB achieving a gain of 8.39dB with better radiation characteristics.

In recent years, the analysis of microstrip patch antenna (MPA) has bloomed the wireless communication. Since there are more compact gadgets in the wireless technology, more antenna come into existence with varying configuration and space orientation. The compactness proposed for the design of MPA becomes more challenging task for proper alignment, flexibility in feeding the line. MPA finds more advantageous than the earlier antenna with huge structures, which are likely installed at the proper height. The proposed radiator analysed for three shapes (rectangle, circle and triangle). In addition, the radiator analysed for different substrates such as Arlon, Epoxy, FR4, Polymide and Rogger 5880 using the software CST studio software 2019. The height if the dielectric layer is 1.6 mm.

“…The CP bandwidth generated by both the antennas is very narrow along with comparatively large size. Similarly, another equilateral triangular microstrip antenna has been designed in [15] that generated a circularly polarized bandwidth after the introduction of three triangular optimum-sized slots on the ground plane. The designed antenna has higher gain than the same dimension antenna with a truncated tip, but the CP bandwidth generated by it is narrow along with comparatively large size.…”

In this research work, a low-profile microstrip patch antenna has been designed with broad circularly polarized resonant bandwidth. The designed antenna consists of an equilateral triangularshaped radiating patch with two triangular coplanar parasitic elements along with a square-shaped ground plane. The unique feature of this antenna design is a generation of circularly polarized radiation by only optimum corner truncation of the two parasitic elements along with a small portion of the driver patch. The designed antenna can be used for (5.725-5.850 GHz) WLAN and (5.85-5.925 GHz) dedicated short-range communication applications with circularly polarized radiation property. The overall resonant bandwidth for (S 11 ≤ −10 dB) is 1.52 GHz 24.75% with a frequency range (5.38-6.90 GHz), and the circularly polarized resonant bandwidth for (Axial ratio ≤ 3 dB) is 240 MHz 4.13% with a frequency range (5.69-5.93 GHz). The gain of the antenna is 4 dB at 5.81 GHz and almost remains the same for the entire resonant bandwidth. The complete design of the antenna has been done using theoretical calculation and HFSS ver13 simulation software. After that, it has been fabricated, and different parameters have been measured using Vector Network Analyser. It has been found that the measured results are very much similar to the simulated results.
