A high-gain, wideband antenna element that covers most portions of X- and Ku-bands is essential for multimode radar applications. This letter presents an aperture-coupled stacked patch antenna for 8.75-12.25-GHz frequency band. Fixed beam tilt up to 30 ° in scan range can be obtained by offsetting the aperture relative to a driven patch. When there(More)
Wideband, planar and low profile antenna array is proposed and designed for Ku band direct broadcast from satellite reception for mobile systems. Contrary to earlier designs, the array antenna covers entire downlink Ku-band frequencies (10.8-12.75 GHz) for simultaneous reception from multiple transponders. The array antenna exhibits 16.5% bandwidth and has(More)
Integrated Global Positioning System (GPS) and Satellite Digital Audio Radio (SDARS) antenna is proposed for automotive use. The GPS antenna is formed by modifying an annular ring antenna operating at TM<sub>12</sub> mode, and the SDARS antenna is placed at the ring center using a slot-loaded degenerate mode TM<sub>11</sub> square patch. The GPS antenna(More)
Bandwidth, gain, and HPBW are the most essential design characteristics in antenna design. Other features such as cross polarization ratio, front-to-back ratio, in-band gain ripple, electrical height, and physical dimensions also play a critical role in the design. It is difficult to define a common figure-of-merit (FOM) that includes all these metrics, but(More)
Ku band reception systems for mobile platforms demand stringent requirements for the electrical and mechanical characteristics of the antenna. Limitations on height and weight for a rugged antenna design require a careful phased array antenna design. We present a new phased array antenna design capable of mechanical scanning in azimuth and electronic(More)
Aperture coupled phased array antenna design at Ku band is introduced. The array spans entire Receive Band of Ku band (10.8 GHz - 12.75 GHz) and has a gain greater than 24.5 dBi with approximately 330&#x00D7;70&#x00D7;25 mm (LxWxH) dimensions. Low loss waveguide-microstrip type hybrid feed network is also designed and simulation results are presented.(More)
Low noise amplifier design for receiver terminal of Ka Band VSAT systems is presented. The design achieves less than 0.95 dB noise figure at 19.7-20.2 GHz, receive band of Ka band satellite communications systems. Typically, low noise block is used for this purpose, however, in this particular VSAT arrangement, reflector antenna is located away from the(More)
TPMS (Tire Pressure Monitoring System) is becoming an industry standard for driving safety and fuel efficiency. The receiving antenna for TPMS resides in the near field of the sensor antenna and this makes it very difficult to establish a reliable RF link for large vehicles. In the design of receiving antenna, it is paramount to consider the electric field(More)
