“…Table compares the performance of the proposed unit cell directional antenna with other broadband slot antennas reported in the literature. From the table, it is inferred that the proposed antenna is the most compact slot antenna with high fractional bandwidth compared to References . The antenna in Reference offers 37% bandwidth in the wideband mode and 10% bandwidth in the dual‐band mode.…”

This article presents the design, fabrication, and testing of a broadband directional slot antenna and its application in a vehicular environment. The proposed antenna consists of a slot antenna fed by a simple microstrip line. Broadband impedance matching is achieved by replacing the conventional microstrip line with a modified microstrip line. The modified microstrip line consists of a microstrip line terminated with an impedance transformer and a square patch. The proposed antenna offers 76.9% bandwidth centered around 4.8 GHz covering most of the communication applications between 3 and 6.75 GHz. Furthermore, the antenna's radiation pattern is shaped to obtain the desired directional characteristics using a simple reflector and array of via holes. The typical gain enhancement is 2.45 dBi at 5 GHz. This gain enhanced slot antenna is further used to construct the four‐element MIMO antenna. The proposed MIMO antenna configuration offers omnidirectional coverage with realized antenna gain greater than 6 dBi making the antenna more suitable for the vehicular environment. The prototype antenna and the MIMO array are fabricated and measurement results are presented. The measurement results are in good agreement with the simulation results.

In this article, a substrate‐truncated microstrip circular patch antenna with shorting vias is proposed for X‐band applications. The bandwidth of the designed antenna is substantially increased by making two slots—one circular and another annular ring—at the top of the structure which actually helps in bringing two individual resonating frequencies closer to each other. The antenna is simulated using the Ansoft HFSS, and various parameters are optimized for better performance. The deigned structure is finally fabricated and tested, and the measured data fairly agree with the simulated results. The measured relative impedance bandwidth (|S11| < −10 dB) is found to be 28.5% (8.9‐11.85 GHz). The proposed antenna is behaving like a monopole with the radiated beam of conical shaped in the entire operating band having a maximum gain of 7.2 dBi.

Apart from these typical antennas structured with PCB fabrication, some monopolar antennas with air substrate were also proposed to have wider bandwidths. In Ref.…”

A new center‐fed dual‐layer circular patch antenna is proposed for bandwidth enhancement. The proposed antenna consists of a circular ground plane, a slotted circular patch on the lower layer and a parasitic circular patch on the top layer. The slotted circular patch is fed with a coaxial probe. With the help of the slots introduced to the lower patch, the parasitic patch on the top layer is strongly coupled. With the strong coupling of the two patches, a broadband is obtained. A prototype is fabricated. The measured results show that a wide bandwidth of 25% is obtained. Within the bandwidth, the measured peak gain is in the range of 6.2–8.7 dBi. The antenna produces an omnidirectional pattern in the horizontal plane, similar to that generated by a conventional monopole antenna. © 2016 Wiley Periodicals, Inc.
