This paper presents comparison of rectangular micro strip patch antenna and E-Shaped micro strip patch antenna operating at 2.45GHz. Two parallel slots are made into the basic rectangular patch design of micro strip antenna which resulted into desired E-shaped patch. The basic design consist of inset feed type and we have used dielectric substrate Fr4 epoxy whereas E-shaped patch consist of coaxial probe and RT Duroid as substrate. Both the designs have been implemented using HFSS software. On comparing the parameters of both the antenna’s design, it was observed that E-shaped patch antenna has enhanced gain and return loss, hence the antenna with enhanced parameters is considered, the better one.

5G is the advanced high-speed and reliable fifth generation wireless communication better than 4G. In this paper, using FEKO software we have designed and analyzed circular microstrip patch antenna for 5G communication and its applications. The main purpose of this paper is to analyze the design of a circular microstrip patch antenna at 28.5 GHz resonant frequency with microstrip feed line so that it becomes useful for 5G applications. Therefore, we have used Rogers RT/Duroid 5880 substrate material having dielectric constant $\varepsilon_{r}=2.2$ and loss tangent of 0.0010 with substrate height =0.6 mm. After analyzing the design, we have found this method is highly efficient and reliable with respect 5G applications and thus we have obtained good return loss of −32.86 dB, increased bandwidth of 1.6369 GHz, high gain of 10 dB, excellent antenna radiation efficiency of almost 100%.

This paper had been comparing the performance of the normal patch antenna with single complimentary SRR patch antenna. Four different shapes of single complimentary split ring resonator structure had been incorporated into the microstrip patch antenna - square, circular, triangular, and rhombic. This simulation works had been done in CST Microwave Studio simulation software. The operating frequency of this antenna is 2.40 GHz for Wireless Local Area Network (WLAN) application. The parameters that considered in these works are return loss, resonant frequency, input impedance, gain, radiation pattern and bandwidth. The focusing parameter is to achieve the best gain performance that obtained from the single complimentary split ring resonator patch antenna. The addition of square SRR onto patch antenna will improve the gain from 6.334 dB to 6.508 dB.

This paper presents the design and analysis of a broad-band patch antenna using split ring metamaterial. The SRR metamaterial structures are embedded in a unique and novel way in the patch antenna, so that subwavelength modes get introduced in the patch cavity and a broad bandwidth antenna with good performance characteristics is obtained. A rectangular microstrip patch antenna is taken as a reference antenna, which resonates at a frequency of 5.2 GHz and has an impedance bandwidth of 70 MHz. To improve the bandwidth of the patch antenna, firstly the split ring resonator (SRR) is designed according to the reference patch antenna. The optimized SRR metamaterial is placed in between the patch and ground plane of the proposed antenna. The – 10 dB impedance bandwidth of the metamaterial-embedded proposed antenna is 1.63–4.88 GHz and has an average gain of 4.5 dB. The Prototype of the proposed antenna and reference antenna is fabricated and experimental results are obtained. Experimental and simulated results are in good agreement. The presented antenna can be used for LTE, GSM, WiMAX, Bluetooth, and other wireless applications.

The proposed patch antenna is structured as dual rectangle shapes like the eye glass shape. The size of the antenna substrate is 15mm * 25 mm * 1.4 mm in order to ensure the miniaturized properties of the antenna. The bottom side of the substrate is printed with a microstrip feed line, and the copper is the material of the antenna.

The microstrip antenna has a great attention in wireless application because it has different shapes to design. In this paper the square shaped patch antenna is designed with different material for the substrate to improve the efficiency of the antenna. The substrate with high permittivity couples the power into the surface wave that leads to the decrease in efficiency and increases the return loss to overcome this problem substrate with photonic band gap structure is used to weaken the surface wave mode and to improves the efficiency and reduces the return loss. This is due to the periodicity in the dielectric medium. The design of microstrip patch antenna is done by the CST (computer simulation technology). The result gives the lower return loss will be considered as the efficient one. The analyses should be done for different substrate to get the efficient antenna.
