Compact Circularly Polarized Patch Antenna Using a Composite Right/Left-Handed Transmission Line Unit-Cell [PDF]

open access: yes, 2013
A compact circularly polarized (CP) patch antenna using a composite right/left-handed (CRLH) transmission line (TL) unit-cell is proposed. The CRLH TL unit-cell includes a complementary split ring resonator (CSRR) for shunt inductance and a gap loaded ...

Mixer-Duplexer-Antenna Leaky-Wave System Based on Periodic Space-Time Modulation

open access: yes, 2016
We present a mixer-duplexer-antenna leaky-wave system based on periodic space-time modulation. This system operates as a full transceiver, where the upconversion and downconversion mixing operations are accomplished via space-time transitions, the ...

Miniature Wideband stacked microstrip patch antenna based on the sierpinski fractal geometry [PDF]

open access: yes, 2000
The main interest in the design of a miniature microstrip patch antenna (MPA) is its small size in conjunction with the well-known advantages of a MPA (cost, profile, weight).

Compact Tunable Bandpass Filter With Wide Tuning Range of Centre Frequency and Bandwidth Using Short Coupled Lines

open access: yesIEEE Access, 2018
A new compact microstrip tunable bandpass filter with continuous control of center frequency and bandwidth is proposed in the paper. The proposed design is based on short parallel-coupled lines, which are tuned by properly loading varactors.
