## Abstract A novel slot antenna of large bandwidth and small size, which is fed by a fanβshaped microstrip feed with a straight stub, is introduced. The effect of the fan feed on the impedance characteristics is investigated theoretically and experimentally. Good agreement between the theoretical

Figure 10 Frequency drift as a function of the dc voltage applied to the active antenna oscillator. Voltage is varied from nominal V s 6 cc V to V s 4.5 V cc network, a standard MPIE technique using the multilayered media Green's functions is implemented. Once the scattering matrices of both compon
A circularly polarized antenna, realized in a low-cost technology with an integrated feed, is presented for the land-mobile satellite seruice. This antenna presents large bandwidth, high gain, and good axial ratio in all frequency ranges.
## A new and simple technique for obtaining circular polar-( ) ization CP radiation of a single-feed microstrip antenna is demonstrated. This CP design is achie¨ed by insetting a single slit to the boundary of the microstrip patch, and placing a single feed along an axis 45Рto the one containing
## Abstract In this Letter, a dualβfeeding structure with microstrip and an Hβshaped aperture feeding for a microstrip antenna is proposed to achieve high isolation with high gain, easy feeding, and few layers. The measured isolations of the proposed single and 1 Γ 4βarray antenna along the E plane
curves still follow each other closely as the incident angle is varied. ## 4. CONCLUSION In summary, we have studied the nonlinear transmission of a periodic structure containing alternating layers of positive-index and negative-index materials. The gap associated with a zeroaverage refractive ind
