“…The aforementioned radii are proportionally related to the eigenvalues of the TM 11 and TM 21 modes, which are 1.841 and 3.054 [2], respectively. Previously, shorting vias were employed for the miniaturization of TM 02 circular patch antennas [3]. The size reduction of MPAs may also be realized by dielectric loading, as any increase in the permittivity can help reduce the guided wavelength of the antenna.…”

A miniaturized TM 21 mode circular patch antenna is introduced. The miniaturization is realized by loading the patch with four symmetric radial slits, which facilitate elongating the current path and thus reducing the resonant frequency and the patch size. In particular, the eigenvalue of the proposed higher order mode is reduced to that of a conventional dominant TM 11 mode antenna, resulting in about 40% reduction in the radius. The effects of the slit geometry on miniaturization and resonant frequency are studied. The measurement results are also presented, which are in good agreement with the simulation ones. Such miniaturized TM 21 patch antennas with conical radiation patterns have manifold applications in phased array antennas for booming communication demands.

“…3D meandered shaped radiators or multilayered printed circuit board (PCB) fit well in such cases; see, for instance, [1,2]. On the other hand, low-cost designs call for the use of single-layered PCB, restraining the antenna to be at most "2.5D" shaped, with vias or other short connections between the front and the back planes [3]. Sometimes, not even a back metal plane is present, leaving no choice for the antenna but to be planar.…”

Among the present technologies for WLAN devices, USB dongles still play a noticeable role. One major design challenge regards the antenna, which unavoidably has to comply with a very small volume available and sometimes should also allow multiband operation. In this scope, the present work discusses a dual-band WiFi compact planar IFA-based antenna design for a low-cost USB dongle application. Like most of the related published solutions, the methodology for deriving the present proposition was assisted by the use of an antenna analysis software. A prototype was assembled and tested in order to qualify the radiator design. Practical operation conditions were considered in the tests, such as the influence of the dongle case and the effect of the notebook itself. The results complied with the design constraints, presenting an impedance match quite stable regardless of the stick position alongside a laptop base.

“…En la figura 5 se detallan dos antenas microstrip triangular y circular con sus respectivos modelos miniaturizados por simetría usando postes de corto circuito, con una frecuencia de operación unificada. Los parches con postes de corto circuito son usados donde no hay suficiente espacio para un parche estándar [12,23,65], también son usados cuando se requiere un plano E más amplio, debido a que no forma un arreglo con el otro borde radiante, aunque esto aumenta la radiación de polarización cruzada [64].…”

“…Las técnicas de miniaturización se pueden clasificar en: simetría, ranuras, forma del parche, cargas con componentes concentrados y distribuidos, material del sustrato y algunas mas modernas como los electromagnetic band-gap (EBG) y los metamateriales. La primera de estas técnicas, denominada por simetría consiste en ubicar puntos de simetría mediante el uso de postes metálicos entre el plano de tierra y el parche radiante [11,12,[22][23][24]. Estos postes metálicos causan un desplazamiento del punto de voltaje nulo del centro del parche a los bordes del mismo, lo que hace resonar a este a una frecuencia menor y en consecuencia la antena logra una reducción de tamaño, generalmente a un cuarto de la longitud de onda [22,23].…”

En la actualidad, las antenas parche microstrip han encontrado diversas aplicaciones en comunicaciones inalámbricas y radar debido a su bajo perfil, bajo costo y métodos relativamente sencillos de fabricación. Aunque populares para estas aplicaciones, las antenas microstrip son difíciles de miniaturizar ya que su frecuencia de resonancia está determinada por el modo dominante TMZ 110 presente en la región inmediatamente por debajo del parche.
