Abstract A dual band monopole antenna with triangle stubs operated at 28/38 GHz applications is introduced. The introduced dual band antenna is used for next 5G applications. The introduced antenna is designed on a Rogers RT 4003 with height h = 0.203 mm, dielectric constant ɛr = 3.55 and over dimensions of 12×12×0.237 mm3. The simulated results show that the presented design has two bands, the first one is from 25.9 to 30.4 GHz and the second is from 36.4 to 40.2 GHz with peak gain of 4.54 dB, 4.21 dB in the first and second frequencies respectively. The simulated radiation efficiency for the first and second frequencies is 94% and 96.6%, respectively. There are some small discrepancies between simulated and measured findings due to the fabrication and measurement equipment.

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.

Author have studied various design techniques to design multiband patch antenna. Proximity coupled technique was found more suitable and efficient to design a multiband antenna. This proposed designed antenna is able to operate in two distinguished frequency that means proposed antenna is a dual band antenna with large bandwidth and high directivity. This proposed design contains a defected ground, a rectangular patch and a meandered feed, which is designed to connect a SMA connector. Designed antenna is a 3 layer device having higher radiation intensity at 1.96 and 2.6GHz.

Rectangular Microstrip Patch Antenna

This study describes the design of dual rectangular microstrip patch antenna for Wi-Fi and WiMAX wireless communication applications. In this work, the technique of design array patch antennas was used in order to improve the physical antenna characteristics for Wi-Fi and WiMAX device. As a result, the proposed technique causes to increase the gain and directivity of the antenna. Using this method also leads to enhance measurement bandwidth of antenna and some other antenna parameters as mentioned in this research paper. A dual-band microstrip patch antenna is developed for WiMAX/Wi-Fi wireless applications that operate at a minimum frequency of 2.4 GHz and a maximum frequency band of 3.5 GHz with its dimensions is L= 88.27 mm, W= 171.4 mm and h= 1.67 mm. The achieved parameters of dual patch array antenna for 2.4 GHz and 3.5 GHz are (gain of 8.25 dB, directivity of 10.4 dBi, measurement bandwidth of 65.82 MHz and measurement return loss of -20.86 dB) and (gain of 7.56 dB, directivity of 8.76 dBi, measurement bandwidth of 98.96 MHz and measurement return loss of -21.38 dB) respectively.
