TL;DR: In this article, the authors proposed broadband impedance matching as a natural way to increase the bandwidth of conventional microstrip patch antennas and found that by using an optimally designed impedance-matching network, the bandwidth can be increased by a factor of at least 3.9, the exact value depending on the degree of matching required.

TL;DR: In this paper, an accurate and numerically efficient model for the rectangular microstrip antenna is presented, which concerns a transmission-line model which features the following three major improvements with respect to earlier such models: the mutual radiative coupling (both real and imaginary parts) between the equivalent slots is fully taken into account; the influence of the side slots on the radiation conductance is taken implicitly; simple analytic expressions are introduced for all relevant model parameters.

TL;DR: In this paper, a simple design theory is presented and a practical example is described which operates between 11 and 12 GHz and a novel feeding technique is presented which circumvents the difficulties.

TL;DR: In this article, an antenna for the reception of electromagnetic radiation, for example, microwaves emanating from a geo-stationary broadcast-satellite, the antenna comprising a receiving member and a focusing member forcusing the incident radiation, the receiving member comprising at least one receiving element having an insulating substrate plate, a conductive plate applied to one surface thereof and a flat, conductive pattern applied to the other surface thereof.

TL;DR: In this article, the authors describe a new design method for a wideband array of log-periodically scaled microstrip resonator antennas, which consists of an open-circuited feed line with a branch line connected to each radiating element.
