“…Cross-polarization can be reduced by loading the shorting pins, which has been demonstrated for patch antennas [32][33][34][35]. The shorting pins are located in the centerline of a square patch to strengthen the surface current density near the feeding point at edge.…”

Demand for antennas that are compact and operate over an ultra-wideband (UWB) frequency range is growing rapidly as UWB systems ofer high resolution imaging capability and high data rate transmission in the order of Gb/s that is required by the next generation of wireless communication systems. Hence, over the recent years the research and development of UWB antennas has been widely reported in literature. The main performance requirements sought from such antennas include: (1) low VSWR of <2; (2) operation over 7.6 GHz from 3 to 10.6 GHz; and (3) good overall radiation characteristics. Signiicant size reduction and low manufacturing cost are also important criteria in order to realize a cost-efective and miniature system. Other desirable requirements include compatibility and ease of integration with RF electronics.

“…A convenient way to overcome this limitation consists of using a hybrid microstrip patch, as described in [9,[16][17][18][19][20][21]. In this publication, hybrid microstrip antennas fed by a coaxial probe are predesigned via the cavity model.…”

“…In this publication, hybrid microstrip antennas fed by a coaxial probe are predesigned via the cavity model. Although this model had been previously utilized [9,16,18,22,23], the systematic determination of adequate design criteria has not been fully carried out yet. Such is the primary goal of this work.…”

Based on the equivalent resonant cavity model, an effective analysis methodology of probe-fed hybrid microstrip antennas is carried out in this paper, resulting in a better understanding of the parameter interrelations affecting their behavior. With that, a new design criterion focused on establishing uniform radiation patterns with balanced 3 dB angles is proposed and implemented. Results obtained with the proposed model closely matched HFSS simulations. Measurements made on a prototype antenna, manufactured with substrate integrated waveguide (SIW) technology, also showed excellent agreement, thus validating the use of the cavity model for predesigning hybrid microstrip antennas in a simple, visible, and time-and cost-effective way.

“…Accurate results can also be obtained for shorted microstrip antennas using cavity model and this was presented for circular patch antennas [17,18]. Rectangular microstrip antennas can be designed to have their non-radiating edges shorted to ground to significantly reduce cross polarized radiation and was recently analyzed using the cavity model [19]. Compact designs and larger impedance can also be achieved using a secondary coupled patch with shorting posts implemented in both the primary and secondary patches [20].…”

Abstract-An extended transmission-line model is presented for an inset-fed rectangular microstrip patch antenna. The transmission-line model agrees to the cos 4 impedance variation for inset-fed microstrip antennas with an addition of a corrective extended feed length upto the inner radiating edge. Verification of the model's complex reflection coefficient is concluded with good agreements with measured results. Further extension of the transmission-line model with for or more thin shorting post connected to multiple varactor diodes have been conducted. Fourty two test cases across five independent antenna designs have been worked upon. Results obtained using the transmission-line model are compared with those obtained with a 3D full-wave solver and measurements. In 69% of the test cases, the transmission-line models have less than 3% deviation to the measured or simulated results. 41% of them have less than 1% deviation. For the first two antennas, both simulated and measured results were compared with the transmission-line model. For the rest of three, results from the transmission-line model were compared to the simulated ones.
