“…As empirically presented in Reference , the length L of the prototype dipole is specified as 1.5‐wavelength . If the range of length L can be more rigorously determined in theory, a more generalized design approach would be developed as expected.…”

“…Figure and Equation imply that the length of the prototype dipole must be the integer multiples of the one‐half wavelength, rather than other arbitrary values. If the two radii are left open, and L is set as 1.5 λ (where λ is the wavelength at the center resonant frequency), the specific case presented in Reference would be resulted in: the only difference is that the alternating sequence of the circumferential cosine‐ and sine‐dependency in Equation would be interchanged, the fundamental mode would exhibit a sine circumferential dependency instead. Therefore, the proposed approach presented in this article should be more rigorous in theory and more generalized in design than that in Reference .…”

“…Most of the multi‐resonant, wideband patch antennas exhibit relatively bulk sizes of about one wavelength . More recently, multi‐resonant, wideband circular sector patch antennas with more compact size are designed as evolving from a straight prototype dipole . Circular sector patch antennas with multi‐resonant characteristics have been proved to be possible candidates for compact designs .…”

“…However, this may lead to multilayered structure with higher configuration complexities. It is noted that the proposed design approach in Reference is generalized only when the length of the prototype dipole is empirically specified as 1.5‐wavelength . If more compact antenna size with low profile is required and the antenna configuration should be maintained as simple as possible, a more generalized, low‐complexity approach for compact designs would be essentially desired.…”

In this work, a generalized design approach to compact, wideband multi‐resonant microstrip patch antenna is proposed. Theoretical criterion of the length of the prototype dipole is laid down based on the simplest dipole model and the associated eigenmodes at first. Then, the criterion is employed to reveal the general relationship between the prototype dipole length, operational modes, sizes, and radiation behaviors of the resultant multi‐resonant circular sector patch antennas. Next, a compact wideband, dual‐resonant circular sector patch antenna is designed accordingly. It is operating at the TM3/4,1 and TM9/4,1 modes within a 240° circular sector patch radiator with its radii short circuited. The antenna fabricated on a single‐layered air substrate exhibits an available radiation bandwidth of 25.0%, with a profile as small as 0.043 guided wavelength at the center frequency. It is evidently verified that the approach can be employed to realize compact, dual‐resonant wideband microstrip patch antennas without increasing antenna profile, inquiring multiple radiators or employing reactance compensation techniques. In addition, it may lead to a series of novel wideband patch antenna designs with diverse performances.

“…But, the gain and other radiation characteristics of this configuration have not been investigated. Recently, novel approach was reported to enhance BW of the single MSA by combining several resonant modes simultaneously using slots, with differential‐fed on stepped‐impedance resonator, by aperture fed method loaded with shorting posts, and Sectoral angle/radius …”

Half‐hexagonal microstrip antenna (H‐HMSA) is a compact version of HMSA, as it resonates at the same fundamental mode frequency. In this article, a compact configuration of a single layer, broadband gap‐coupled H‐HMSA has been proposed. Gap‐coupled H‐HMSA is fed indirectly by a λ/2 microstrip‐line resonator. Broad bandwidth (BW) is achieved with an effective use of resonance introduced by λ/2 resonator and gap‐coupled half‐hexagonal radiating patches. A peak gain of 7.07 dBi and measured BW (S11 ≤ −10 dB) of 11.5% at the center frequency of 5.2 GHz have been achieved, which occupies a small volume of 0.023 λ03 including the ground plane. The radiation patterns remain in the broadside direction throughout the return loss BW. Simulated results of the proposed antenna configuration are experimentally validated with good agreement.

Summary This paper presents the design of a dual‐band circular patch antenna for the application requirements of wireless handheld devices and various wireless sensor modules operating in WiMax and 5G NR Bands. The design originated from a single‐band conventional circular patch antenna and ended up with a dual‐band circular patch. A novel hexagon‐shaped slot was preferred to achieve dual‐band performance in the circular patch antenna. The simulation level performance of the antenna is verified using the Advanced Design System 2019 tool. An FR4 material with a height of 1.6 mm is selected as a substrate for the patch antennas. The return loss and radiation pattern behaviour of the patch antennas are measured using a network analyser and an anechoic chamber. The fabricated prototype achieves dual‐band performance at 3.47 and 6.96 GHz. Simulated and measured results show that the proposed hexagonal‐shaped slot in the circular patch provides a dual‐band behaviour.
