The evolution of advancement in communication technologies and ever-increasing demand by users for compact communication devices has necessitated a shift in the design approach to achieve antenna structures that are compact and robust. Owing to the diverse communication requirements, antenna systems operating across wide bands have become a necessity. An antenna that is capable of working effectively in several bands is called wideband antenna. In this work, a bio-inspired microstrip antenna (Bi-MPA) for wideband application is proposed and simulated. The radiating patch of the proposed Bi-MPA is the shape of Carica Papaya leaf. The structure was realized through the perturbation of the circular shape patch. The proposed antenna has an impedance bandwidth of 4.3 GHz (1.9 GHz–6.2 GHz) at a return loss of 10 dB while it exhibits a narrow band at 7.2 GHz (6.99–7.44 GHz) and 9.3 GHz (9.15–9.35 GHz) bands. The gain of the proposed antenna is between 2.60 dB and 10.22 dB and the radiation pattern is quasi-omnidirectional. The proposed Bi-MPA is compact and suitable for global system for mobile communication (GSM1900), Universal Mobile Telecommunication System (UMTS), Wireless Local Area Network (WLAN), Long Term Evolution (LTE2300 and LTE2600), Worldwide Interoperability for Microwave Access (WiMAX), C-band, X-band, and sub6 GHz fifth-generation (5G) band. Our contribution to the scientific community in this work is that we have proposed a single antenna structure that is suitable for communication in all the bands mentioned in order to ensure compactness in the mobile devices as compared to base station antennas.

A compact broadband folded dipole antenna element with a ball grid array packaging is proposed in this letter. The compact antenna element is fabricated on a low-cost FR4 substrate consisting of only one dielectric layer. The solder balls are mounted on the square ground metal plane of the antenna element to form the ball grid array (BGA) packaging, which allows the antenna element to be surface mounted with other surface-mount devices (SMDs). Furthermore, ball grid array packaging has great potential for minimizing the size of antenna elements. The dimension of the proposed antenna element is only 6 mm × 6 mm × 1.6 mm. Parameter analysis shows that the solder balls have little effect on antenna performance. The proposed folded dipole antenna element is fed by a 50 Ω grounded coplanar waveguide (GCPW) transmission line on the evaluation board. The antenna prototype has been designed, analyzed, and manufactured. Measured results of the prototype show that the −10 dB impedance bandwidth is 45.4% , and the peak gain achieves 6.62 dBi at 35 GHz. The measurement results show that the proposed antenna element has great potential for the 5G millimeter wave application.

In this paper, a simple wideband unidirectional antenna is proposed. The antenna is originated from the basic magneto‐electric (ME) dipole antenna. A pair of half‐wavelength horizontal patches are used to excite the basic electric dipole mode. In order to excite the basic magnetic dipole mode, the horizontal patches are extended inward. As a result, the quarter‐wavelength vertical patches are well excited and the impedance matching is improved in the high frequency band. In addition, a pair of vertical patches are employed, it can not only reduce the resonant frequency of the basic electric dipole mode but also form a new magnetic dipole mode at low‐end frequency. Therefore, the impedance matching in the low frequency band is further improved. The proposed antenna is fabricated and measured. A wide bandwidth of 100% from 2.0 to 6.0 GHz for VSWR <1.5 is obtained. Across the entire bandwidth, the gain is 5.6 ± 1.3 dBi, the front‐to‐back ratio (FBR) is >10 dB. Moreover, the radiation patterns are stable, symmetrical, and have no side lobe. The proposed antenna is suitable for wideband unidirectional wireless systems.
