Umbrella Monopole Antenna (UMA) proposed in this paper for 5G application. We designed four models of UMA, i.e: UMA-A, UMA-B, UMA-C, and UMA-D. The antenna has a curvature in the patch as an umbrella shape with a feeding shape a microstrip feed line. Four variations of the patch antenna have been designed and get different performance in VSWR, surface current, and directivity. The proposed antenna has a wide bandwidth that operates 8 GHz – 30 GHz with VSWR <2 dB. The Increasing of directivity is reached for UMA-A, UMA-C, UMA-D, and UMA-B, i.e: 6.38 dBi, 7.97 dBi, 8,84dBi, and 9,15 dBi respectively at 24 GHz.  The maximum gain has been reached for UMA-B of 9.15. The lowest frequency that has a return loss of 10 dB has resulted for UMA-D in the frequency around 5 GHz. All of the UMA antennas can be applied for 5G mmwave applications at 24 GHz and 28 GHz.

Microstrip Feed

A modified proximity-coupled microstrip patch antenna with broad impedance bandwidth is proposed by incorporating proximity-coupled patch antenna into the rectangular open-ended microstrip feed line on a cavity structure. First we design a proximity-coupled microstrip antenna to have a wide bandwidth in the lower band centered at 7 GHz using a cavity-backed ground. To broaden the bandwidth of the antenna to the upper band, we then apply a rectangular open-ended microstrip feed line, adjusting the relative position to the cavity to generate an additional resonance close to 10 GHz. The combination of lower and upper band design results in a broadband antenna with dimensions of 30 mm × 30 mm × 9 mm (0.9λ<sub>0</sub> × 0.9λ<sub>0</sub> × 0.27λ<sub>0</sub>) is designed where λ<sub>0</sub> corresponds to the free space wavelength at a center frequency of 9 GHz. The measurement results verify the broad impedance bandwidth (VSWR ≤ 2) of the antenna at 77% (5.6–12.6 GHz) while the broadside gain is maintained between 6 dBi and 8 dBi within the operational broad bandwidth.

Wide Usage

The narrow bandwidth of microstrip antenna is one of the important features that restrict its wide usage. This paper presents a bandwidth enhancement using slot geometry for the feed line matching is proposed and experimentally studied. The maximum bandwidth can be achieved by keeping the optimum distance between the two slots and by adjusting the length of the transmission feed line 50 Ohm. Return loss of -77.74 dB with VSWR 1.0026 for frequency at 940 MHz. The results show that the proposed antenna has the i m p r o v e d impedance bandwidth covering whole band.

Abstract In this research article, the design of a broadband monopole antenna with triband notch characteristics is proposed. Notch characteristics are achieved by using an E-shaped slot on the patch and a U-shaped slot on the 50 Ω microstrip feed line. An E-shaped slot is introduced on the metal patch to reject one frequency band of 6.6 − 7.5 GHz and when an additional U-shaped slot is introduced on the microstrip feed line, it provides two-notch frequency bands of 4.8 − 5.7 GHz and 14.2 − 17.5 GHz. The notch bands are effectively used to avoid undesired interference from the WLAN, C band, and Ku band. The proposed antenna provides a very broad frequency range from 3.3 − 19.5 GHz except for three notch bands. The antenna is small in size and easy to design with only a volume of 29 mm × 21mm × 1.6 mm. The antenna is useful for broadband applications.
